Start the simulation with this distribution of players:

The payoffs in a one-on-one game are:

reset payoffs

Play [N] rounds per one-on-one game

Play [N] round per one-on-one game

After each tournament, eliminate the bottom [N] players & reproduce the top [N] players

After each tournament, eliminate the bottom [N] player & reproduce the top [N] player

In each round of a one-on-one game, there's a [N]% chance a player makes a mistake

Tit For Tat

I Cooperate on the first round. Then, I just do whatever you did the last round. If you Cheat me, I'll Cheat you back &em; but if you Cooperate, I'll forgive you immediately!

Always Cheat

Ain't I a stinker?

Always Cooperate

💖 💖 💖

Grudger

I'll always Cooperate... until you Cheat me even once. Then, I'll always Cheat you back. NO FORGIVENESS.

Prober

First: I analyze you. I start: Cooperate, Cheat, Cooperate, Cooperate. Then: if you retaliated with a Cheat, I switch to playing Tit For Tat. But: if you never fight back, I Cheat the heck out of you. My dear Watson: elementary.

Tit For Two Tats

I Cooperate on the first round. After that, if you Cheat me... well, I'll forgive you once. However, if you Cheat me twice in a row, then I'll Cheat back. (But again, if you Cooperate, I'll forgive you immediately!)

Pavlov's Dog

I Cooperate on the first round. After that, if you Cooperated in the previous round, I'll just do what I did last time (even if it was a mistake). But if you Cheated in the previous round, I'll do the opposite of what I did last time (even if it was a mistake).
