متن کاملResearches on Ingeniously Behaving Agents
We have been studying the techniques for evolutionary robotics and experimenting with various robots applied evolutionary methods. We have paid special attentions to real robots and multi-agent problems with them. In this research domain, we named them as “Ingeniously Behaving Agents (IBA)”. This paper shows several techniques developed in our IBA laboratory and their experimental results appli...
