Study Notes
- Game theory studies mathematical models of strategic interactions among rational agents.
- Game theory has applications in economics, political science, biology, and computer science.
- Game theory studies the behavior of agents in strategic settings.
- In a strategic setting, an agent's actions affect others' outcomes.
Prisoner's Dilemma
- Two suspects are arrested, and the police offer them a deal due to lack of evidence.
- If one confesses and the other doesn't, the confessor is freed, and the other gets 10 years.
- If both confess, they each get 5 years.
- If neither confesses, they each get 1 year.
Payoff Matrix for Prisoner's Dilemma
| Suspect B Confesses | Suspect B Stays Silent | |
|---|---|---|
| Suspect A Confesses | -5, -5 | 0, -10 |
| Suspect A Stays Silent | -10, 0 | -1, -1 |
Algorithmic Game Theory
- Algorithmic game theory combines game theory and algorithm design.
Motivation for Algorithmic Game Theory
- Classical game theory often ignores computational aspects.
- Real-world games are often too complex to solve manually.
- Algorithms can find or approximate game-theoretic solutions.
Topics in Algorithmic Game Theory
- Mechanism Design: Designing games with desirable properties.
- Price of Anarchy: Measuring efficiency loss due to selfish behavior.
- Computation of Equilibria: Finding Nash equilibria and other solution concepts.
Network Routing Example
- A network has $n$ users routing traffic from source $s$ to destination $t$.
- Each user chooses a path, and the cost depends on the traffic on that path.
- Users aim to minimize their own cost, affecting others' costs.
- Question: How much does selfish behavior degrade the network's overall efficiency? This is a "price of anarchy" question.
