Emergence and suppression of cooperation by action visibility in transparent games
Fig 7
i(A)CG strategies in the final population.
Strategies are taken for the 109-th generation and averaged over 80 runs. This figure characterizes the final population as a whole and complements Table 2 representing specific strategies. (A): Strategy entries s1, …, s4. The decrease of the s2/s3 ratio reflects the transition of the dominant strategy from challenging to turn-taking for psee = 0.0, …, 0.4. For psee = 0.5 the dominance of the Leader-Follower strategy is indicated by s2 = s3 = 1. (B) Entries s5, …, s8 are irrelevant for psee = 0. Values of s6, s7 decrease as psee increases, indicating an enhancement of cooperation in i(A)CG for higher transparency (s8 is almost irrelevant since mutual accommodation is a very rate event, and s5 is irrelevant for a population of L-F players taking place for psee = 0.5). (C) Entries s9, …, s12 are irrelevant for psee = 0. The decrease of the s10/s11 ratio for psee = 0.1, …, 0.4 reflects the transition of the dominant strategy from challenging to turn-taking.
