Game theory is a branch of logic which deals with cooperation and conflict in the context of 
negotiations and payoffs. The theory of games can elucidate the incentive conditions required for 
cooperation, can aid understanding of strategic decisions of nations or actors in conflict, and can 
help in the development of models of bargaining and deterrence.
