Considering the external resource offered by environment is limited, here, we will explore the cooperation on spatial networks with limited resource. The individual distributes the limited resource according to the payoffs acquired in games, and one with resource amounts is lower than critical survival resource level will be replaced by the offspring of its neighbors. We find that, for larger temptation to defect, the number of the dead decreases with the resource amount. However the cooperation behavior is interesting, the lower total resource and intermediate temptation to defect can greatly promote the cooperation on square lattice. Our result reveals that the limited resource contributes most to the cooperation.
考虑到环境提供的外部资源是有限的，在此，我们将探讨资源有限的空间网络上的合作。个体根据在博弈中获得的收益分配有限资源，资源量低于临界生存资源水平的个体将被其邻居的后代取代。我们发现，对于较大的背叛诱惑，死亡个体的数量随资源量的增加而减少。然而有趣的是，较低的总资源和中等的背叛诱惑能够极大地促进方格上的合作。我们的结果表明，有限资源对合作的贡献最大。
