Cooperation evolution in structured populations by using discrete PSO algorithm

Abstract

Social dilemma is a challenge to many scientists. The Prisoner’s Dilemma and Snowdrift game were the most used social dilemma models in the cooperation evolution. A particularly effect to the evolutionary process comes from population structure. By comparing population structures that amplify selection with other population structures, both analytically and numerically, we show that evolution also affected by the cost to benefit ratio and neighbor number.
