Coevolving Strategies in Social-Elimination Games

Social games provide a framework to study how individuals and groups of individuals interact with each other, and develop strategies to achieve their own well-defined objectives. This paper provides a co evolutionary analysis of how different strategies evolves in a class of social games. We describe a new formalism for modeling a player that is capable of learning and adapting its strategies to act with the other members of its own group and against those of a conflicting group. We define two example player models based on the formalism. We also propose a methodology to compare different player models using co evolution. Our experimental results show that different groups develop, in an alternating fashion, counter-strategies against the other groups over time and the performance a player depends on the player´s ability to adapt to its opponent´s strategies.
