The behavior selection of artificial life based on evaluation-tradeoff structure

Through the analysis of current reactive/deliberative structures, based on schema theory, according to bionics, this paper provides a new behavior selection structure. Firstly, simply analyses the existing methods of behavior selection; Secondly, introduces the behavior selection structure based on evaluation-tradeoff in detailly and proposes two concepts, namely perception satisfied degree and exhibition desired degree; Finally, taking soccer robot as experiment platform, describes the method on how to design behavior, analyses the experiment results which proves the validity of structure proposed in this paper. Simulation experiment results show that, based on this new behavior selection structure, the artificial life not only imitates the natural life behavior realistically in unknown environment, but also has higher dynamic programming intelligence.
