- Abstract:
-
We investigate the adaptation of cooperating strategies in an iterated
Prisoner's Dilemma (IPD) game. The deterministic IPD describes the
interaction of N agents spatially distributed on a lattice, which are
assumed to only interact with their four neighbors, hence, local
configurations are of great importance. Particular interest is in the
spatial-temporal distributions of agents playing different strategies,
and their dependence on the number of consecutive encounters n_g during
each generation. We show that above a critical n_g, there is no
coexistence between agents playing different strategies, while below
the critical n_g coexistence is found.
