Cooperation in Evolutionary Public Goods Game on Complex Networks with Topology Change

TL;DR

This paper investigates how the interplay between game dynamics and changing network topology influences the evolution of cooperation, defection, and payoffs in public goods games on complex networks.

Contribution

It introduces a model where network topology evolves under game dynamics and analyzes its effects on cooperation and payoffs through computer simulations.

Findings

Network topology changes can promote cooperation.

Interaction between game dynamics and topology affects average payoffs.

Initial network structures evolve into different configurations due to game influences.

Abstract

The evolution of cooperation among unrelated individuals in human and animal societies remains a challenging issue across disciplines. It is an important subject also in the evolutionary game theory to research how cooperation arises. The subject has been extensively studied especially in Prisonars' dilemma game(PD) and the emergence of cooperation is important subject also in public goods game(PGG). In this article, we consider evolutionary PGG on complex networks where the topology of the networks varies under the infulence of game dynamics. Then we study what effects on the evolution of player's strategies, defection and cooretation and the average payoff does the interaction between the game dynamics and the network topology bring. By investigating them by making computer simulations, we intend to clear in what situations cooperation strategy is promoted or preserved. We also intend to investigate the infuluence of the interaction on the average payoff over all players. Furthermore how initial networks are transformed to final networks by the evolution through the influences of PGG dynamics is invistigated.
