A simulation of an evolving collection of players of the iterated prisoner's dilemma.

When people co-operate, things usually turn out well. If no-one co-operates, then everyone usually suffers. So the game plan is obvious, right?

Wrong! If everyone else is co-operating, then some clever fellow will come along and take advantage. So now the game plan is obvious, refuse to co-operate and take advantage of everyone who is naively co-operating.

Stupid! This is so obvious that no-one will co-operate, will they? And, yes, everyone will suffer.

This is clever?

This is a famous dilemma, with all sorts of significant analogies in the real world from Mutaually Assured Destruction to the Tragedy of the Commons to the evolution of ethics in a godless universe.

There is a very simple solution, though it only becomes perfectly obvious by using mathematical simulation.
