Probability and Game Theory¶
Summary¶
Bayesian reasoning provides a framework for quantifying and updating beliefs based on evidence. Game theory studies strategic decision-making in competitive and cooperative interactions, with Tit for Tat emerging as the simplest winning strategy for repeated games.
Related Concepts¶
| Concept | Summary |
|---|---|
| Bayesian Reasoning | Prior × likelihood / total evidence → posterior |
| Tit For Tat | Cooperate first, then copy opponent; wins iterated games |
| Prior Probability | Belief before evidence; the base rate |
| Posterior Probability | Belief after evidence; the updated probability |
