Prisoner’s Dilemma - Tournament Simulation

Always cooperates, regardless of what the opponent does.

Always defects to maximize its immediate advantage.

Starts by cooperating, then copies the opponent's previous move.

Cooperates by default and retaliates only after two consecutive defections.

Mirrors cooperation, but responds to defection with a 90% chance of defecting.

Chooses between cooperation and defection at random each round.

Probes with cooperate–defect–cooperate, then adapts to patterns in the response.

Tests the opponent in its opening moves, then adjusts based on the pattern it sees.

Cooperates until it is exploited, then retaliates on the next move.

Opens cooperatively, then seeks opportunities to defect while reacting to success.
