Emotion model with evolution process

This paper proposes a decision making system derived by evolution process. The proposed system acts as if it has an emotion. Recent researches on emotion have shown that emotion is the most reasonable decision making system for maintaining the individual and its species. If it is able to generate this system artificially, it may be applicable to various engineering fields. Conventional approach to artificial emotion is to analyze emotional expression of human being and to simulate this expression. The structure of the simulation model is determined artificially without the knowledge of actual emotion system. However, recent cognitive science understands that emotion system cannot be described previously, but it can only be derived by evolutions. Thus, such simulation model without considering evolution may not be proper. On this point of view, we propose a decision making system derived by evolution process.
