Many problems in human society reflect the inability of selfish parties to cooperate. The "Iterated Prisoner's Dilemma" has been used widely as a model for the evolution of cooperation in societies. Axelrod's computer tournaments and the extensive simulations of evolution by Nowak and Sigmund and others have shown that natural selection can favor cooperative strategies in the Prisoner's Dilemma...

In this paper, a Cooperative Network Game (CNG) is introduced. In this game, all players have the same goal: display a video content in real time, with no cuts and low buffering time. Inspired in cooperation and symmetry, all players should apply the same strategy, resulting in a fair play. For each strategy we shall define a score, and the search of the best one characterizes a Combinatorial O...

Spectrum sharing in cognitive radio networks is essential to ensure effective communication between secondary users. Game theory is suitable to be applied to the spectrum sharing strategies since it considers strategic interactions between users. There are two types of games based on the ability to communicate between users: cooperative game and non-cooperative game. In this paper, the two spec...

Cooperative data forwarding can improve the performance of data routing in Mobile Social Networks (MSNs). However, previous studies mainly assumed that mobile nodes show selfish behaviors in data relaying merely due to their limited device resources. Nevertheless, the observation of everyday experience infers that they mitigate their selfishness based on their social relationships and content k...

In this paper, an efficient multi-objective model is proposed to solve time-cost trade off problem considering cash flows. The proposed multi-objective meta-heuristic is based on Ant colony optimization and is called Non Dominated Archiving Ant Colony Optimization (NAACO). The significant feature of this work is consideration of uncertainties in time, cost and more importantly interest rate. A ...

In this paper, we aim at investigating from a game theory perspective whether trade liberalization can promote a collusive intra-industry trade and whether such a collusive trade is always socially desirable compared to the autarchy solution. We show that, under Cournot competition, economic integration is anti-competitive if collusive trade is a possible outcome of the repeated game; under pri...

Abstract Today, debt stabilization in an uncertain environment is an important issue. In particular, the question how fiscal and monetary authorities should deal with this uncertainty is of much importance. Especially for some developing countries such as Iran, in which on average 60 percent of government revenues comes from oil, and consequently uncertainty about oil prices has a large effec...
