COOPERATION AMONG VIRTUAL ANTHROPOIDS IN A COMPLEX ENVIRONMENT

The process of EIA falls under article 6 of the Aarhus Convention as a form of public participation during the preparation of a project. The Aarhus Convention recognises that public participation in decision-making enhances the quality and the implementation of decisions, gives the public the opportunity to express its concerns, and enables public authorities to take due account of such concerns. The EIA Directive should ensure that the public gets sufficient information about the project and its environmental impacts in an understandable form and that it has sufficient time to study it and to send comments. Concerned members of the public should have the opportunity for timely. | Interdisciplinary Description of Complex Systems 9 1 56-80 2011 COOPERATION AMONG VIRTUAL ANTHROPOIDS IN A COMPLEX ENVIRONMENT Jakson Alves de Aquino Department of Social Sciences Federal University of Ceará Fortaleza Brazil Regular article Received 31.

Anthropoid agents reproduce sexually and live in a world where food is irregularly distributed in space and seasonally produced. They can share food form hunting and migrating groups and are able to build alliances to dispute territory. The agents memorize their interactions with others and their actions are mainly guided by emotions modelled as propensities to react in specific ways to other agents actions and environmental conditions. The results revealed that sexual reproduction is extremely relevant in the proposed model cooperation was stronger between agents of opposite sex.

However I think that the goal of building realistic models of the evolution of cooperation in the human species would also be worthwhile. My goal in this paper is to offer a contribution to this approach by building a model of evolution of cooperation among virtual anthropoids with realistic assumptions about the agents minds and their ecological environment. My emphasis in this model is on the agents instinctive propensities to feel emotions rather than on the evolution of cognitive abilities to make rational decisions. The knowledge required to make realistic challenges came from many disciplines. .
