The Tournament
Design a strategy for the Prisoner's Dilemma — and enter it into Axelrod's round-robin against the famous eight. The twist you'll watch happen: betrayal wins every match and loses the war.
1 — Design your strategy
Open with…
Your very first move, before you know anything.
Retaliate?
Punish the opponent when they defect on you.
Hold a grudge
Once provoked, defect forever (like Grudger).
Patience
Defections it tolerates before striking back.
1
Memory
How many recent opponent moves it watches.
1
Forgiveness
Chance to offer peace instead of striking back.
Wildness
Chance it throws a random move of its own.
