Dealing with Parameterized Actions in Behavior Testing of Commercial Computer Games

Abstract- We present a method that enhances evolutionary behavior testing of commercial computer games, as introduced in [CD+04], to deal with parameterized actions. The basic idea is to use a layered approach. On one layer, we evolve good parameter value combinations for the parameters of a parameterized action. On the higher layer, we evolve at the same time good action sequences that make use of the value combinations and that try to bring the game in a wanted (or unwanted) state. We used this approach to test cornerkicks in the FIFA-99 game. We were able to evolve many parametervalue-action sequence combinations that scored a goal or resulted in a penalty shot, some of which are very short or represent a rather unintelligent behavior of the players guided by the computer opponent.
