多群

A multi-agent/mobile-agent platform, which stems from computational infrastructure agent grid has been designed and prototyped. As a node of grid, on each platform simulations of evolutionary processes of multi-nodes synchronous processing associated with individual inter-generation communication and individual migration between elementary populations can perform coadaptation based cooperative coevolution of the multi-population as a whole system, such as the case of the three species ecological system.

In order to solve dynamic, complicated and uncertain problems, multi-agents based distributed intelligence decision support systems, description and decomposition of complicated decision tasks, and cooperation and reasoning among multi-agents are elaborated in this paper. The details are given as follows. 1. Agent and ABDIDSS modelsIn allusion to the current problems of research on agents theory models, payoff and probability factors are introduced on the basis of mental state models of classical BDI of agent and joint BDI of multi-agents in this paper, mental state models of individual agents and joint metal state models of group agents based on payoff and probability factors are built up.
