Prisonner's Dilemma
Principle
- Each player aims is to gain the maximum points.
- There will be 4 rounds of play, each lasting 5 turns.
- For each round, each player will be paired with another player. These player will play together Iterated Prisonner's Dilemma.
Iterated Prisonner's Dilemma - Scoring
- Each turn, the two players choose between "Volunteer" and "Defect". Their reward is based on the two player's choice:
- At the end of a round, a player score is the sum of its score at each turn.
- Players that end with a round score strictly lower than 0 lose an additional 10 points.
- Final score of a player is the sum of all its round scores.
- Players are ranked according to their final score.
Other rules
- Unless otherwise stated, players can speak with each other in anyway at any time. I would enjoy if each player pair use the provided quicktopic so that I can reveal everything at the end.
- The first turn of each round will last 48 hours. All other turns will last 24 hours.
- After each turn, I will reveal the choices publicly in the thread.
Special Round rules
After the first round, each round will some additionnal rules:
Round 2 rules wrote:* Players are not paired randomly
* At the beginning of the round, you have 2 days to find a partner. Once you find a partner, both of you must state so in the thread, and you will play the round together.
* Players that have not found a partner with get a -10 penalty after the two days are elapsed and will be paired randomly
Round 3 rules wrote:* Players are paired randomly with someone they didn't already play with.
* Players can't communicate with each other once the pairing are known.
Round 4 rules wrote:* Players are paired together according to current ranking
* This round will last 50 turns instead of 5
* Payouts of each turn are divided by 10, except the last ten, which are only divided by 5.
* You have two days to discuss with your partner.
* After the two days, you must give my an algorithm to decide whether you Volunteer or Defect, based on your opponent previous choice. I will run the two algorithms myself.
Mod Notes
This game should be correctly balanced, as no breaking strategy should exist. Actually, it can be shown that a perfectly rational player will always lose the game. If you feel you have found a loophole in the rules, you are welcome to notify me.
Signups
- Signups will be open for minimum 3 days and until at least 6 players have joined.
- If more than 6 players join during the 3 days and this number is odd, I will wait until a last player joins, in order to have an even number of playes.
- Anyone is welcome, but I ask that each player tries to do its best. If I feel a player is only there to help/damage another player, I reserve the right to remove this player. You are obviously not allowed to join with two accounts.
