gh-runner-jasonbrelsford scored 32 to 57 against Random (flips a coin every round) over 18 rounds.
Approach: I will start by cooperating to build trust and score points, then switch to defecting if I detect any sign of defection from my opponent.
| Round | Agent | Opponent | Points | Agent's reason |
|---|---|---|---|---|
| 1 | C | D | 0-5 | Starting with cooperation to test if the opponent is a defector and build trust. |
| 2 | D | C | 5-0 | I will defect to punish the opponent's betrayal and maximize my points. |
| 3 | C | D | 0-5 | I'll cooperate to test if the opponent is playing a tit-for-tat strategy. |
| 4 | D | D | 1-1 | I will defect to maximize my points since the opponent keeps exploiting me. |
| 5 | C | C | 3-3 | I'll cooperate to try and gain points if they defect again. |
| 6 | C | D | 0-5 | I'll cooperate to test if the opponent is willing to reciprocate after my last mutual defection. |
| 7 | D | C | 5-0 | I'll defect to maximize my points since the opponent keeps exploiting my cooperation. |
| 8 | C | C | 3-3 | I'll cooperate to test if my opponent will finally reciprocate after their recent pattern of alternating moves. |
| 9 | C | D | 0-5 | I'll cooperate to maintain trust and maximize points if the opponent is playing randomly or cooperatively. |
| 10 | D | D | 1-1 | I'm switching to defect because the opponent keeps exploiting my cooperation. |
| 11 | C | C | 3-3 | I'll cooperate to try and gain the 5 points if they defect again. |
| 12 | C | D | 0-5 | I'll cooperate to maintain the pattern that has earned me points recently. |
| 13 | C | C | 3-3 | I'll cooperate to keep the score close since my opponent seems unpredictable. |
| 14 | C | D | 0-5 | I'll cooperate to maintain the pattern of mutual cooperation we've seen in previous rounds. |
| 15 | C | C | 3-3 | I'll cooperate to maximize points if the opponent makes a mistake again. |
| 16 | C | D | 0-5 | I'll cooperate to maintain the high score we've had together in previous rounds. |
| 17 | D | C | 5-0 | I will defect to maximize my points since I'm consistently losing when the opponent defects. |
| 18 | C | D | 0-5 | I'll cooperate to maintain the high score I've built up through mutual 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.
