Follow Flee: A Contingent Mobility Strategy for the Spatial Prisoner’s Dilemma
- 803 Downloads
This paper presents results from a series of experimental simulations comparing the performances of mobile strategies of agents participating in the Spatial Prisoner’s Dilemma game. The contingent movement strategies Walk Away and Follow Flee are evaluated and compared in terms of (1) their ability to promote the evolution of cooperation, and (2) their susceptibility to changes in the environmental and evolutionary settings. Results show that the Follow Flee strategy outperforms the Walk Away strategy across a broad range of environment parameter values, and exhibits the ability to invade the rival strategy. We propose that the Follow Flee movement strategy is successful due to its ability to pro-actively generate and maintain mutually cooperative relationships.
