Editing Artificial intelligence

'''Artificial intelligence''', abbreviated as '''AI''', in the [[Super Smash Bros. (series)|''Super Smash Bros.'' series]] refers to the intelligence of any computer-controlled (CPU in ''Brawl'' and later, CP in ''64'' and ''Melee'') character (called '''computer players''' in-game) in the [[Single Player modes|single-player]] and [[Versus Mode]]s. In Versus Mode, players can preset the AI of a computer player with a level setting. In [[Adventure Mode]], [[All-Star Mode]], and [[Classic Mode]], players can still set it to some degree with the modes' difficulty setting.

Artificial intelligence levels range from 1 to 9, with 1 being the weakest and 9 being the strongest. The default CPU level in Versus matches is 3 for ''Smash 64'' and ''Brawl'', and 1 for ''Melee''. In general, the level of an AI opponent determines how likely they are to follow through with a decision, as well as how fast they react, which results in the illusion of more skill - both a Level 1 and a Level 9 AI will decide to do something such as input an attack, but the level 1 will almost never do so, while the level 9 almost always will. Lower level CPUs are also unlikely to [[shield]] or [[dodge]] an attack; in ''Melee'', they roll only for shifting directions, and in ''Brawl'', they randomly and occasionally use their shield as their almost only form of defending. On the other hand, higher level ones almost always defend from attack, generally having good reflexes or dodging any attack when not in lag - this is most pronounced in ''Brawl'', where Level 9 CPUs can dodge almost any attack with one-frame reaction, resulting in disproportionate [[perfect shield]]ing capabilities. Higher level ones also vary more between attacks: low-leveled ones just move around the foe and randomly input an attack, usually a ground attack or special attack, while high-leveled ones are by far more aggressive and rely more on stronger attacks such as aerials or grabs. Their [[recovery]] also improves as their level is increased: CPUs at low levels tend to recover in a simple and predictable pattern with their [[up special]]s, or may not use them at all in ''Smash 64'', while high-level ones in ''Brawl'' are capable of properly combining or alternating between different recovery techniques.

In [[Training mode]], besides attacking, CPUs also have many other "modalities" that can be chosen, these being: [[Stand]], [[Evade]], [[Walk (mode)|Walk]] and [[Jump (CPU Mode)|Jump]]. When these are chosen, CPUs will act that way, allowing players to battle in different ways against them, and practice different types of techniques. In ''Smash 64'' and ''Melee'', these are set to a pre-determinated level (levels 3 and 1 respectively), while in ''Brawl'', they can be chosen from 1 to 9 from the character selection screen as usual, which also improves their reflexes. For example, Level 1 CPUs on Stand will just take on whatever attack is thrown on their way, and recover in a simple and [[gimp]]able pattern, while Level 9 ones will almost always air dodge after [[tumbling]] and will choose better recovery options. When set to Attack, CPUs will fight the player as on usual battles, but since the level cannot be selected in ''SSB64'' and ''Melee'', it is somewhat unfavorable to fight CPUs on Training mode. Players instead tend to train against them on normal Versus modes.

Certain 1-player stages and [[event]]s in ''Melee'' give CPUs a level of 0, such as [[Event 19: Peach's Peril]] and [[Event 21: Ice Breaker]], in which case they don't attack at all, but still follow whatever movement behaviour they would normally have.

The [[amiibo]] figures to be released with {{forwiiu}} have stored data for a CPU fighter within them. The player may [[character customization|customize]] said character and train them by having them battle. The amiibo is labelled with "FP", and can gain experience to level up after battle, capping at Level 50. It has been stated that battling amiibo against each other will yield more experience than battling a human or regular CPU. Additionally, the amiibo will be able change tactics after repeated battles.

Training against CPUs is said to not adequately train one's skills beyond basic offense and defense (such as the ability to read and bait opponents), and it is often argued that excessive CPU training may cause a player to actually become slightly worse by developing habits that only work against CPUs and will be heavily exploited by human players. For example, if a Kirby player persistently used [[Stone]] on a CPU, it would be hit by the attack most of the time, without defending against or punishing it, and do no more than occasionally dodge it, even at level 9. However, a skilled or even a remotely competent human player would easily avoid the attack by rolling, sidestepping, shield-grabbing or just walking away, and then punish Kirby with a grab or strong attack, such as a charged smash. Another example is CPUs not fighting off edge-guarders in any of the Smash games, which allows players to KO them with basic edgeguarding techniques, while experienced players would prevent this at all costs.

However, training against CPUs does have its merits. CPUs can be used to effectively practice [[combo]]s and [[chain throw]]s, as well as [[spacing]], [[punish]]ing and other [[tech skill]] related things. CPUs can be more effective than human players in this regard, as they're always available and won't refuse a match where a player just wants to practice the aforementioned things. Many top professional smashers have reported using CPUs to train, such as {{Sm|Nairo}}, {{Sm|Vinnie}}, and {{Sm|Mew2King}}.

There is, however, no consensus as to which level CPU is best to train against, with players mostly having their own personal opinion on what level is most effective. Some say level 1 CPUs are the best, as they won't have inhuman perfect shielding abilities and won't disrupt the player's training. Some say level 9 CPUs are the best, as they will actively try to fight the player and can punish mistakes the player makes. Some others say level 5 CPUs are the best for being a middle ground between the two extremes. Another camp maintains what level is best is dependent on what a player is trying to practice.

{{split|This section alone is 73,460 bytes, AI flaws are different each game, each subsection is large enough to warrant its own page, I believe.}}

 

While it is notable that high level CPUs are precise with their reflexes, such as being able to perfect shield almost any attack, reflect projectiles with little hesitation, counterattack out of [[knockback]] the instant they can act, and land or control attacks that human players would find difficult such as Yoshi's [[Egg Throw]] and Pikachu's [[Volt Tackle]], all three games are known for having AI that can be extremely flawed in most scenarios, even when set to level nine. CPUs also never use techniques that are complex or otherwise require specific timing, such as [[edgehogging]], [[chaingrab]]ing and [[edge hop]]ping, nor use other such advanced techniques, such as [[L-cancel]]ing, [[wave dash]]ing and [[DACUS]]ing, which are crucial for achieving strong results in competitive play. There are many complaints surrounding the poor artificial intelligence of computer players in ''[[Super Smash Bros.]]'' and ''[[Super Smash Bros. Melee]]'', though ''[[Super Smash Bros. Brawl]]'' has also received attention to its flawed AI system; in all three games, particularly noteworthy and amusing AI flaws have been uploaded to YouTube, often while saying that the AI in the games is "just too good".

 

 

 

 

 

 

 

 

 

*When standing on moving platforms, CPUs usually won't be conscious about the danger and will stay there like on a normal terrain, which mostly results on them not jumping off and going offstage with the plaftorm, guaranteeing a self-destruct. This can happen, for example, when a CPU comes to attack a foe on the balancing plaftorms at {{SSB|Mushroom Kingdom}}, or when landing on an Arwing during recovery at [[Sector Z]].

 

 

 

 

The AI is also extremely incompetent with handling [[item]]s and their effects. The AI will ignore any changes made to their physique and will play as if they were normal, which leads to instances where they often will self destruct simply by trying to move, such as [[giant]] CPUs inadvertently walking off stages, and [[metal]] CPUs plummeting to their death as they attempt to attack an offstage player. CPUs also do not recognise items, so they will never pick them up when one appears, only doing so accidentally when trying to attack an opponent next to the item; additionally, they will always walk into set [[Motion-Sensor Bomb]]s, walking [[Bob-omb]]s, and hostile [[Poké Ball]] Pokémon. When picking up battering items (except for the Hammer), the AI still acts and fights as if not wielding it, which often leads into CPUs jabbing persistently with the item and then dropping or throwing it in an attempt to grab opponents. There is an exception to this when there are healing items, [[Poké Ball]]s, [[Cloaking Device]]s, or [[Hammer]]s present; CPUs will usually immediately cease all fighting against the player and will instead flee to pick up these items. They will often put themselves in harm's way while trying to do so, just to obtain said item. Additionally, they don't attempt to grab items while in the air, so if the item falls on a platform, for example, the CPU will pick it up only after landing on it, while a human player would [[air grab]] it from below, making easy to snatch items away from CPUs.

1. Avoid adding very specific, situational instances that rarely, if ever, show up, where a computer player may not perform optimally. If you have to specify what level the CPU is, the character, the stage, what the CPU is attempting, and even the exact location on the stage, do not add it. Also do not add examples that require nonstandard gameplay, and do not add examples that you have to write a small guide to replicate.

2. Suboptimal play by the CPU in general does not constitute an AI flaw. For something to be considered an AI flaw, it has to be a repeated behavior by the AI that directly hinders a CPU's performance regardless of outside circumstances.

3. Per the previous guideline, a potential example must be a behavior by the CPU that it will nearly always repeat when the circumstances leading to the example occurs.

4. Examples are ordered, so when putting down an example, make sure it fits the order. The order goes; general flaws > character specific flaws > item related flaws > stage related flaws > character + specific stage flaw.-->

***{{SSBM|Luigi}} acts as an exception; he will instead always use the [[Green Missile]] and never use [[Super Jump Punch]] to recover, even when necessary. He also never charges the former move, so he will most likely fail to recover if the attack is not a misfire, even though the move is used periodically. This leads to CPU Luigis self-destructing easily on stages that emphasise vertical recoveries, like [[Mushroom Kingdom II]] or [[Brinstar Depths]].

**They never use the second hit of {{SSBM|Link}}'s or {{SSBM|Young Link}}'s forward smash; as a result, CPUs have more difficulty KOing with both characters, as Link's forward smash is relatively weak when the first hit connects, while Young Link's first hit deals low, set knockback to set up the second, more powerful attack.

**A CPU Kirby under the effect of [[Stone]] will never end the transformation early. Besides allowing players to easily punish a CPU Kirby with powerful attacks, this will cause him to self destruct on some stages; if he hits a breakable platform above the lower blast line or is on a slope that ends offstage, he will end up sliding down and plummeting offstage.

*CPUs will always throw a grabbed opponent in a random direction, which, combined with their excessive use of throws, results in CPUs throwing the foe into the stage while attempting to edgeguard, or using a certain throw when a different one would have KO'd the foe. Some CPUs also tend to overuse a specific throw, such as Fox overusing his [[down throw]], or Mario and his clones frequently using their [[back throw]]s.

*AI players have poor taunting habits. After the CPU respawns, if the player was previously KO'd by it will occasionally walk to the player and taunt for no apparent reason.

**Upon KOing a character, CPUs will usually taunt, regardless of what is occurring around them. Additionally, when KOing an enemy horizontally from the middle of a main platform, they will walk to the edge nearest to where the KO occurred before taunting. When Star KOing an opponent, they won't taunt until the animation is finished, leaving them unnecessarily vulnerable during long taunts.

*CPUs will never initiate a [[dash]] except to perform [[dash grab]]s and [[dash attack]]s, the latter being less common. In this case they act almost immediately after the initial dash, which makes their attack pattern predictable and easy to avoid.

*While CPUs always attempt to dodge certain attacks (as noted above), their dodges are often poor in these cases. For example, a CPU near an edge attempting to dodge an attack such as Bowser Bomb may still roll towards the edge, which can result in the attack still hitting and KOing the CPU while it would have survived with another dodging technique.

**When [[air dodging]], CPUs also tend to shift themselves in the direction they were already moving, or may not move at all, even if it causes them to unnecessarily fail to avoid the attack they were trying to.

*CPUs never attempt to intentionally execute wall or ceiling [[tech]]s, the former being accidentally triggered when they are near a wall and attempt to shield too late. They also use ground techs only if they are sent on an upwards trajectory and are not interrupted before reaching the ground.

*Other than Fox and Falco using their Reflectors, CPUs always reflect projectiles with perfect shields only, even though some characters like Mario and Zelda have more effective [[Reflection|reflectors]]. This results in things such as CPUs not being able to properly reflect Poké Balls (as perfect shielding them does not change the Pokémon's owner) or consecutive projectiles, or their shields becoming easily broken by rapid-fire projectiles.

*CPUs do not recognise pits as if they were an offstage area, leading to the CPU just walking and falling into them as the CPU attempts to carelessly attack an opponent near the pit, which often results in the CPU self-destructing.

*CPU Peaches, Luigis, Pikachus and Pichus tend to use their [[side special]]s against foes near the attack's maximum range, not charging them for the latter three (as noted above). While not seemingly problematic, they can be easily punished if the attack misses, and in Luigi's case, he may self-destruct on small stages if the attack misfires.

*A CPU {{SSBM|Ness}} never uses [[PSI Magnet]]; even when projectiles are shot in his vicinity, he will just reflect them by perfect shielding.

*When CPU Marths and Roys use [[Dancing Blade]] and [[Double-Edge Dance]], respectively, after knocking their foe away with the first hit, they will always execute the three subsequent hits of the attack even if the foe gets out of reach. They also never use the up and down versions of the attacks. If the foe is very close to them and isn't knocked away with the first hit, they may instead only use that one, even when following-up with the others was possible.

**CPU Captain Falcons will additionally always use Raptor Boost after using [[forward throw]] (or sometimes [[down throw]]) on someone, even if it would cause them to go offstage and self-destruct. They may also use Raptor Boost if the player is near the ledge offstage, attempting to hit them, but usually falling off the stage. CPU Ganondorfs however do not exhibit this behavior with Gerudo Dragon.

**CPU Ganondorfs will also nearly always use Dark Dive when someone is nearby and above them, even if they're near the edge of the stage, which can cause them to use Dark Dive and then fall offstage, self-destructing. CPU Falcons generally do not exhibit this behavior with Falcon Dive, but they will often try to Falcon Dive after successfully executing an up throw. This is preceded by a single jump. The entire process is a predictable and thus poor attempt at comboing the opponent.

*CPU Kirbys and Bowsers will mostly use their down specials (Stone and Bowser Bomb respectively) on foes below them when they are in midair, regardless of what is below them. Similarly, some grounded CPUs will spam a special attack if a player is above them: a CPU Ness will spam [[PK Flash]], a CPU Pikachu or Pichu will spam {{b|Thunder|Pokémon}}, and a CPU Peach mostly uses [[Peach Parasol]] if the player is at a close range. CPU Yoshis may also use Egg Throw in a similar way.

*A high level CPU {{SSBM|Yoshi}} mostly uses [[Egg Roll]] against a player at a large distance, and chase him/her even if near an edge, so that if the player dodges or just shields against the attack, the CPU may easily fall offstage and self-destruct.

*A CPU Mewtwo that is charging [[Shadow Ball]] in midair (by either falling off an edge when attacking a foe out of range, or sometimes when using the move very close to one) will never [[Charge cancel|cancel]] the attack, and won't shoot the ball if there are no enemies directly in front of it, simply falling down and self-destructing.

*Whenever a player semi-spikes a CPU Mr. Game & Watch, Zelda, or Mewtwo close to the edge, these three characters will never use their up specials unless they are low and underneath the stage, or are hit by another player, leading to self destructs.

*When CPUs are caped by Mario or Dr. Mario offstage before they use up special after using their midair jump, they will use aerial attacks even if they miss the ledge while using aerial attacks. Depending on the attack's duration, this will cause them to fail a recovery that was possible and self-destruct.

*Picking up either a Hammer or a Starman will cause all the CPUs to run to the opposite side of the stage and stand there until the effect wears off; they will not use any defensive maneuvers whatsoever.

*If a CPU grabs a Hammer, it will chase opponents until they reach a wall and continually jump in place even if the obstacle can be jumped over. It will also jump offstage to chase opponents that have jumped off the stage, and self destruct in the process.<ref>http://youtu.be/FQ7bCnFYpEs</ref>

*If they are next to the radius of [[Venusaur]]'s earthquake or near [[Wobbuffet]], CPUs may shield even though they are not in the Pokémon's damage radius. Unusually, they may also hold their shields in place, which can result in a self-inflicted shield break (Jigglypuff will SD because of its unique [[shield jump]]). This is noticeable with the Wire Frames on the [[Event 37: Legendary Pokémon|Legendary Pokémon]] event.

*When the player stands still on certain locations in stages, all opposing CPUs will cease all movement and action if the player is not in attack range, until the player moves or one of the aforementioned desired items appears<ref>http://youtu.be/X5vjGlJv4BI</ref>. A notable example of this is the right edge of the middle right platform in {{SSBM|Battlefield}}, which can be exploited in [[Cruel Melee]]<ref>http://youtu.be/qFYGCSPKQuk</ref>.

**Also, if the player stands still on the right platform as a CPU Fox comes off the [[revival platform]] in this same stage, Fox will repeatedly jump into the river, use [[Fire Fox]] below the center platform and fail to recover until he runs out of stocks or time runs out<ref>http://youtu.be/i-b3tCc3sn0</ref>. A CPU Roy will also exhibit this behavior in this situation, aiming his [[Blazer]] to the left, missing the ledge and self-destructing<ref>http://youtu.be/4RpldojemmU</ref>.

*On N64 [[Yoshi's Island]], if the player stands on a cloud close to the horizontal blast line, CPUs will go towards them with their usual recovery patterns, commonly not using other clouds at platforms. When using their up special, they will also aim for the closest cloud even if it's out of range, leading to self-destructs.

*On [[Mushroom Kingdom II]], when battling against a level 9 Luigi set as Player 2, if the player KOs him and then goes to the right part of the stage, Luigi will jump backwards from the revival platform and miss the ledge, and then use Green Missile on the wall and self-destruct<ref>http://youtu.be/k3oJLGJ3Qsk</ref>. He will continue this indefinitely until interrupted by an item, [[Pidgit]], or [[Birdo]]'s eggs.

===''[[Super Smash Bros. Brawl]]''===

In ''Super Smash Bros. Brawl'', the AI is generally more proficient with character recoveries (most prominently {{SSBB|Luigi}}). If a human player gets an [[item]] like a [[Starman (item)|Starman]], rather than just trying to avoid that character, they will also use the opportunity to attack any stragglers. When a [[Smash Ball]] appears, computer players will aggressively attack it at opportune times, while repelling anyone who tries to get it as well. They also recognize and use all items as well, unlike in ''Melee''. Additionally, CPUs can now properly charge up or hold smash attacks and special attacks, among others, and choose more alternatives when using certain attacks, such as Kirby spitting out characters more often, Link using his [[grab aerial]] and the second hit of his [[forward smash]], and Donkey Kong throwing foes upwards and/or downwards with his cargo throw instead of just forward. CPUs can now properly use [[aerial attack]]s against grounded foes rather than just attacking from land, and often punish attacking opponents with [[shield grab]]s. Their taunting habits are less flawed than in ''Melee'', as they don't use them if there are other enemies or obstacles, and they won't taunt if the player just escapes from them after they respawn. Additionally, CPUs in ''Brawl'' are much better at defending, as they sidestep and roll more often, and, with the change of air dodges, also use this technique properly, as well as being almost impossible for a human player to break a CPU's shield, and high-level CPUs almost always [[tech]]ing on any solid surface when launched a far distance. Plus, when a Hammer, [[Superspicy Curry]], Starman, dangerous [[Poké Ball|Poké Ball Pokémon]] or [[Assist Trophy]], or [[Final Smash]] is being used by a foe, high-level CPUs will stay on their revival platforms if they were KO'd, instead of just reentering the fight instantly like in the previous games. Another notable change is that, when a high-valued [[item]] appears, instead of just ceasing fighting to go for it, CPUs now try to repel any other character trying to get it, and if it appears too far from them, they will just ignore it and battle as usual (except for the Smash Ball). Even then, CPUs will always walk toward an offstage item, instead of utilising faster movement options.

A new feature in [[Training Mode]] allows the computer's level to be selected. The AI is improved greatly, as opponents set to Attack mode will actively fight the player, rather than walking towards them and rarely throwing an attack like in previous installments. Other CPU modalities can also be improved by raising the AI level.

 

 

 

 

**A CPU {{SSBB|Ness}} or {{SSBB|Lucas}} will always hit themselves with [[PK Thunder]] in the same upward diagonal trajectory when recovering, even if using such a trajectory will result in them failing to make it back to the stage while a more desirable trajectory would allow them to recover successfully. This is especially noticeable on {{SSBB|Final Destination}}, as Ness will often not make it back to the stage when using PK Thunder to recover (when recovery is possible), while a Lucas will often launch himself underneath the stage's lips.

**A CPU {{SSBB|Ike}} will not use [[Aether]] unless he is directly underneath a ledge. This can cause him to self destruct without trying to recover, or waiting too late to use Aether and failing a recovery that was possible. CPU Snakes exhibits similar behavior using [[Cypher]], often choosing to use it too late and self-destruct.

**If a CPU {{SSBB|Mr. Game & Watch}} uses [[Fire]] and fails to recover, he will repeatedly use [[Judge]] until the bottom blast line is crossed. While not necessarily problematic, there are instances where if a CPU Mr. Game & Watch reaches the apex of Fire and ends up short of the stage but in distance of reaching the ledge, the CPU will decide to use Judge too soon, causing him to miss the ledge and self-destruct.

*If a CPU, regardless of level, is hit near the upper [[blast line]] while above an elevated platform, they will fall straight down until reaching the ground after knockback is finished, while making no attempt to dodge or counterattack a pursuing player.<ref>http://www.youtube.com/watch?v=D9nursdpKIw</ref>

*When hit by an electric hitbox, a CPU may randomly DI up or down, more often DIing down, which can result in instances of an attack with an electric hitbox KOing them when the computer player would have survived otherwise.

*If a player gets too close to a CPU while still under the invincibility granted by respawning, the CPU will constantly roll towards the nearest edge, even when jumping or sidestepping is a better option. This is very predictable and often [[punish]]able.

*If a CPU Snake plants a [[C4]] sticky on an opponent, he will always move a small distance away and use Cypher, then detonate the C4 after. This makes them extremely vulnerable, predictable, and [[punish]]able. If attacked out of the Cypher, they will simply run away a short distance and then detonate the C4.

*A low level Fox, Falco or Wolf will mostly self-destruct when using Landmaster, especially if the target is hanging on a ledge. A high level CPU will stay in place and repeatedly perform barrel rolls against opponents grabbing the ledge. Also, regardless of the level, they won't attempt to [[Star KO]] enemies above them by rising, only doing it accidentally when rising on small stages like [[Flat Zone 2]].

**Similarly, a CPU Pit using [[Palutena's Army]] will spam [[Palutena's Arrow]].

*CPU {{SSBB|Sonic}}s, {{SSBB|Yoshi}}s, or {{SSBB|Diddy Kong}}s using [[Super Sonic]], [[Super Dragon]], or [[Rocketbarrel Barrage]], respectively, have the tendency to behave rather eccentrically:

*If a CPU {{SSBB|Jigglypuff}} fails to grab a ledge during their recovery, they have a tendency to repeatedly spam [[Pound]] until they pass the blast-lines.

 

Many rumors have circulated about the AI of ''Brawl''. One rumor claims that level 9 CPUs read button commands the player inputs, thereby allowing them to perfect shield and air dodge more often. This sparked general dislike among the community, many of whom labelled the idea as "cheating". There has been no evidence however that the AI reads the player's inputs, and "evidence" presented for it has just shown that the AI has 1 frame reactions.

 

Another rumor claims that there is a system in ''Brawl'' that enables AI players to "learn" from human players.<ref name="CECPUexpBlog">{{cite web| url = http://allisbrawl.com/blogpost.aspx?id=8848| title = The Wonders of Brawl's CPU Experience System| accessmonthday = Jan 2| accessyear = 2011| author = [http://allisbrawl.com/blog.aspx?id=10347 ChurroEmiliano]| date = 2008-12-31| format = blogpost| work = | publisher = [http://allisbrawl.com/ AllIsBrawl.com]| quote = When developing Super Smash Bros.

}}</ref> [[All is Brawl]] blogger Churro Emiliano documented much of this widely for the first time in a blog post made at the end of 2008. Aside from some advanced techniques (such as [[dash dancing]] and [[DACUS]]ing) and play-styles, the AI have also been reported to "learn" to [[taunt]] a KO by crouch-spamming,<ref name="jerkette">{{cite web| url = http://www.youtube.com/watch?v=diJX703iC0A| title = ...jerkette| accessmonthday = Jan 2| accessyear = 2011| author = [http://www.youtube.com/user/Hoidsa Hoidsa]| date = 2009-05-13| format = video| work = | publisher = YouTube| quote = }}</ref> and to overuse Falcon Punches after humans play several Falcon Punch free-for-alls.<ref name="CEFalconPunch" /> This rumour is demonstrably false for several reasons:

**Disassembling a Brawl save file also reveals that no AI traits are retained in the save.

*If the rumour was true then replays would desynchronise when the AI learned from the player and changed its behaviour after the replay was saved. Replay data does not contain the inputs of the AI; it contains the player inputs, information such as the stage and characters used, and the random seed of the original match. When the replay is played back, the AI determines its actions from scratch in exactly the same way as it did in the original match (the same actions are produced because all variables that would affect the AI's decisions are identical). The replay data has been disassembled to reveal that it does not contain any information about what the AI had learned at the time the match was saved. A learning AI would make different decisions in the replay than it did during the original match, causing the replay to desync, as it would be using its current behaviour (with the adjustments it had made after the original match) and not the behaviour it used in the original match.

*No documented objective tests (for example, only using one move in several matches on a fresh save file and seeing if the AI uses that move significantly more than on a save file which has been used normally) have been performed which have concluded that the learning mechanism exists.

 

 

*CPU {{SSB4|Mii Fighter}}s have a habit of using their jabs near the edge of a stage, in an attempt to edgeguard recovering human players while they're hanging onto a ledge. In the process, they will usually let the jab reach its automatic finisher even if it completely misses (assuming that the player does not climb back onto the stage during the duration of the attack).

**CPUs will rarely use the [[Ore Club]] correctly; when holding it, they will often stand in place and use its forward tilt repeatedly as if expecting this to produce a projectile, even though a side-smash must be used to do this.

**Like in ''Brawl'', CPUs will actively seek out any powerful items that are on the stage. However, this proves to be a fatal issue on [[Corneria]]; in this scenario, a CPU may try to grab an item that falls onto the Great Fox's laser blaster, but will often not be able to make it back onto the ship's deck, forcing them to stay put, (though they will repeatedly jump in place or even jump off the gun entirely only to get back onto it) until they are inevitably blasted off screen.
