Hedonic models of fish behaviour

The project aims at developing a new method for modelling behaviour in an individual-based model. The method evolves affective responses to sensory information, and the organisms are capable of receiving several different kinds of impressions simultaneous ly (e.g. temperature, density of conspecifics, light entensity, prey concentration, as well as signals of state of own organism). Since the method is based on evolved sensory responses, and not on evaluation of fitness choices of decisions (as in classica l evolutionary tools), the method can be used in more complex environments than previous tools. It can also (when the gene pool is adapted), perform decisions in a flat fitness landscape, as long as sensory information can be translated to feelings.
