Abstract
This paper studies scenarios of cyclic dominance in a coevolutionary
spatial model in which game strategies and links between
agents adaptively evolve over time. The Optional Prisoner’s Dilemma
(OPD) game is employed. The OPD is an extended version of the traditional
Prisoner’s Dilemma where players have a third option to abstain
from playing the game. We adopt an agent-based simulation approach
and use Monte Carlo methods to perform the OPD with coevolutionary
rules. The necessary conditions to break the scenarios of cyclic dominance
are also investigated. This work highlights that cyclic dominance
is essential in the sustenance of biodiversity. Moreover, we also discuss
the importance of a spatial coevolutionary model in maintaining cyclic
dominance in adverse conditions.
