Why are only human beings possessing many intellectual abilities among many creatures? The social brain hypothesis shows that human beings have increased their brains while reading the intentions of others. A relationship where each other reads the intention of others, cooperates or betrays it creates intelligence arms race competition. In this study, we simulated this kind of arms race by using evolutionary computation on finite automaton using games with three types of gain tables, and as a result confirmed whether the complexity of the agent is increased. As a result of the analysis, we found that the complexity of the agent ‘s strategy tree which got a high score increased with the gain condition requiring delay to compensation.
The findings of this research can be applied to interaction with artifacts that do not get bored.

数ある生物のうちで、なぜ人間だけが多くの知的能力を持つのでしょうか。社会脳仮説では、人間が他者の意図を読み取る中で脳を増大させていったことを示しています。お互いが他者の意図を読み、協調あるいは裏切りを行う関係は,知能の軍拡競争を生み出します。本研究ではこのような軍拡競争について、３種類の利得表のあるゲームを用い、有限オートマトン上の進化計算を用いてシミュレートし、結果としてエージェントの複雑さが増えるかを確認しました。分析の結果、高いスコアを得たエージェントの戦略木の複雑性が,報酬に遅延の必要な利得条件で増えることがわかりました。
本研究の知見は、飽きのこない人工物とのやり取りなどに応用が可能です。
