Vulcans and Klingons (part one): Simulating an Evolutionary Game with Random Matching and Adjustable Expectations.
The possibility of cooperation in a repeated prisoner's dilemma without memory is investigated in an evolutionary framework where 1) some agents ('Vulcans') are morally commited to cooperation, 2) some others ('Klingons') are not commited at all, and 3) there is random matching.
