document: Modeling group foraging : individual suboptimality , interference , and a kind of matching A series of agent-based models support the hypothesis that behaviors adapted to a group situation may be suboptimal -LRB- or `` irrational '' -RRB- when expressed by an isolated individual . These models focus on two areas of current concern in behavioral ecology and experimental psychology : the `` interference function '' -LRB- which relates the intake rate of a focal forager to the density of conspecifics -RRB- and the `` matching law '' -LRB- which formalizes the observation that many animals match the frequency of their response to different stimuli in proportion to the reward obtained from each stimulus type -RRB- . Each model employs genetic algorithms to evolve foraging behaviors for multiple agents in spatially explicit environments , structured at the level of situated perception and action . A second concern of the article is to extend the understanding of both matching and interference per se by modeling at this level
