軍隊アリシステムにおける利他行動による探索空間の分割とエージェント数の関係に関する一考察

摘要

An army ant is known to perform the altruism behavior that sacrifices its own benefit and aims the best benefit of group. Such a new ethology is the scientific and objective study of animal behavior. Especially, army ant based multi agent system employs the swarm intelligence technology. In this system, the agents build the bridge using thier own bodies on the obstacle such as a ditch. We find the characteristic pattern that the agents search for the shorter path from the nest to the food while other agents cross the bridge. In this paper, we observed ant behaviors around the feeding spots under the environment with 3 spots. According to the search, 2 or more groups were appeared and each group explored the subspace aroundthe feeding spots. We explain the characteristic relation between the number of agent and the dividing search space.
