Agent negotiation over multiple issues is often seen as the process of searching for a solution in a complex and large space. Depending on the negotiation mechanism such search space can be dynamic wherein agents may be cooperative or non-cooperative. In a realistic negotiation, agents are unwilling to reveal their utility functions to their opponents or collaborators. These important character...

We introduce a cooperative co{evolutionary system to facilitate the development of teams of heterogeneous agents. We believe that k different behavioral strategies for controlling the actions of a group of k agents can combine to form a cooperation strategy which eeciently achieves global goals. We both examine the on{line adaption of be-havioral strategies utilizing genetic programming and dem...

This research concems the comparison of different artificial evolution approaches to the design of cooperative behavior in a team of simulated mobile robots co-evolved against a second team. The first and second approaches, termed single pool and plasticiry, are characterized by robots that share a single genotype, though the plasticity approach includes a leaning mechanism. The third approach,...

Recently, many brain-inspired models have been used in attempts to support the cognitive abilities of artificial organisms. In this article, we introduce a computational framework to facilitate these efforts, emphasizing the cooperative performance of brain substructures. Specifically, we introduce an agent-based representation of brain areas, together with a hierarchical cooperative co-evoluti...

Cooperative Inquiry is a Participatory Design method that involves children (typically 7-11 years old) as full partners with adults in the design of technologies intended for use by children. For many years, child designers have worked together with adults in Cooperative Inquiry approaches. However, in the past children have not typically initiated the design problems tackled by the intergenera...
