Punishment has been deemed as a key to solve the puzzle of the evolution of cooperation. Recent studies have suggested that altruistic punishment may be motivated by preference for social equality (egalitarian punishment). Here we construct individual-based models to investigate the effectiveness of egalitarian punishment in promoting cooperation. Based on computational experiments, we first show that egalitarian punishment is as effective as classic punishment, which directly observes others' strategies, in a meta-population model. We then use a scale-free network model to show that egalitarian punishment can be effective even when heterogeneity in the number of interactions among individuals is incorporated. Finally, we show that generosity in punishment can affect co-evolution of egalitarian punishment and cooperation.

Interest Model

Assigning the value of interest to each node in the network, we give a scale-free network model. The value of interest is related to the fitness and the degree of the node. Experimental results show that the interest model not only has the characteristics of the BA scale-free model but also has the characteristics of fitness model, and the network has a power-law distribution property.

The Mean

We introduce a new quantity, relevance-strength which describes the relevance of a node to the others in a scale-free network. We define a weight between two nodes i and j based on the shortest path length between them and the relevance-strength of a node is defined as the sum of the weights between it and others. For the Barabási and Albert model which is a well-known scale-free network model, we measure the relevance-strength of each node and study the correlations with other quantities, such as the degree, the mean degree of neighbors of a node, and the mean relevance-strength of neighbors. We find that the relevance-strength shows power law behaviors and the crossover behaviors for the degree and the mean relevance-strength of neighbors. Also, we study the scaling behaviors of the relevance-strength for various average relevance-strength for all nodes.
