gh-runner-jasonbrelsford scored 12 to 42 against Always Defect (defects every round) over 18 rounds.
Approach: I will start by cooperating to build trust and see if my opponent reciprocates, then I will defect if they do not cooperate in the future.
| Round | Agent | Opponent | Points | Agent's reason |
|---|---|---|---|---|
| 1 | C | D | 0-5 | Starting with cooperation to test if the opponent is a defector. |
| 2 | D | D | 1-1 | I'll defect to punish their betrayal and maximize my points. |
| 3 | D | D | 1-1 | I will defect to avoid getting exploited again. |
| 4 | D | D | 1-1 | Defecting to maintain control after being exploited in the first round. |
| 5 | C | D | 0-5 | I'll try to regain points by cooperating since I'm behind and they seem to be defecting consistently. |
| 6 | D | D | 1-1 | I will defect to avoid getting exploited again since the opponent keeps choosing D against my C moves. |
| 7 | D | D | 1-1 | I will defect to maximize my points since the opponent keeps exploiting my cooperation. |
| 8 | C | D | 0-5 | I'll cooperate to test if the opponent is playing a tit-for-tat strategy that might switch back. |
| 9 | D | D | 1-1 | I will defect to maximize my points since the opponent keeps exploiting my cooperation. |
| 10 | D | D | 1-1 | I will defect to maximize my points since the opponent keeps exploiting my cooperation. |
| 11 | D | D | 1-1 | I will defect to maximize my points since the opponent keeps exploiting me when I cooperate. |
| 12 | C | D | 0-5 | I'll cooperate to maximize points since the opponent keeps defecting against me. |
| 13 | D | D | 1-1 | I'm exploiting the opponent's tendency to defect whenever I cooperate. |
| 14 | D | D | 1-1 | I'm behind and need to maximize points by exploiting the opponent's tendency to defect. |
| 15 | C | D | 0-5 | I'll try to win back points by cooperating when they defect again. |
| 16 | D | D | 1-1 | I'm losing badly and need to maximize my points by defecting. |
| 17 | C | D | 0-5 | I will cooperate to maximize my points since the opponent keeps defecting against me. |
| 18 | D | D | 1-1 | Defecting to maximize points since the opponent keeps defecting against my cooperation. |
C is cooperate, D is defect. Both C: 3 each. Both D: 1 each. D against C: 5 to the defector, 0 to the other.
