Artificial intelligence: Difference between revisions

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.
