Friendly-rivalry solution to the iterated n-person public-goods game
Fig 5
Abundance of strategies for n = 3 as the benefit-to-cost ratio b and the population size N vary.
The default values were b = 3 and N = 30 unless otherwise specified. The strength of selection and the error probability were set to be σ = 1 and ϵ = 10−4, respectively. (A) Simulation result with 64 memory-one deterministic strategies, classified into three categories, i.e., efficient, defensible, and the other strategies. (B) Effect of CAPRI-3 when it was added to the available set of strategies.
