The coalition formation problem arises when heterogeneous agents need to be gathered in groups in order to combine their capacities and solve an overall goal. But very often agents are different and can be distinguished by several characteristics like desires, beliefs or capacities. Our aim is to make groups of agents according to several characteristics. We argue that a swarming method inspired by group dynamics allows groups to be formed on the basis of several characteristics and makes it very robust in an open system context. We evaluate this approach by making groups of heterogeneous cognitive agents and show that our method is adapted to solve this problem.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
