Using the spatial dilemma strategies to model agents' commitments for a coalition formation

摘要

In spatial strategies of a spatial prisoner's dilemma (Ishida and Mori (2005) Artif Life Robotics 9:139-143), it is possible to involve not only the geographical configuration of countries, but also many other relations such as economic relations, historical relations, military relations, and so on if they can be expressed by a network. This article explores the possibility of modeling an agent's commitments using spatial strategies. Several types of spatiotem-poral strategy are discussed in a context of coalition formation in international communities.
