The Evolutionary Price of Anarchy:Locally Bounded Agents in a Dynamic Virus Game The Price of Anarchy (PoA) is a wellestablished gametheoretic concept to shed light on coordination issues arising in open distributed systems. Leaving agents to selfishly optimize comes  :27,risk of ending up in suboptimal states (in terms of performance andor costs), compared to  :43,system design. However, the PoA relies on strong assumptions about agentsxe2x80x99 rationality (e.g., resources and information) and interactions, whereas in many distributed systems  :67,locally with bounded resources.

CoEvolution of Complex Network Public Goods Game under the Edges Rules The reconnection of broken edges is an effective way to avoid drawback for the commons in past studies. Inspired by this, we proposed a public goods game model under the edges rules, where we evaluate the weight of edges by their nodesxe2x80x99 payoff. The results proved that the game obtains a larger range of cooperation with a small gain factor by this proposed model by consulting Monte Carlo simulations (MCS) and real experiments. Furthermore, as the following the course of game and discussing the reason of cooperation, in the research, we found that the distribution entropy of the excess average degree is able to embody and predict the presence of cooperation.
