![]() This popularity extends to AI research, as evidenced by numerous papers and two different competitions. Pac-Man is among the most popular video games of all time. The results demonstrate that MM-NEAT can discover interesting and effective behavior for agents in challenging games. Interestingly, the best networks dedicate modules to critical behaviors (such as escaping when surrounded after luring ghosts near a power pill) that do not follow the customary division of the game into chasing edible and escaping threat ghosts. Both fixed modular networks and Module Mutation networks outperform monolithic networks and Multitask networks. ![]() ![]() Several versions of Module Mutation are evaluated in this paper. The appropriate number of modules can be fixed or discovered using a genetic operator called Module Mutation. Multitask) or discovered automatically by evolution. The modules are used at different times according to a policy that can be human-designed (i.e. In contrast, this paper uses a framework called Modular Multi-objective NEAT (MM-NEAT) to evolve modular neural networks. Pac-Man have treated the game as a single task to be learned using monolithic policy representations. Past approaches to learning behavior in Ms. Pac-Man must escape ghosts when they are threats and catch them when they are edible, in addition to eating all pills in each level. Pac-Man is a challenging video game in which multiple modes of behavior are required: Ms.
