Why are common names considered unreliable for scientific classification?
Why are common names considered unreliable for scientific classification?
- Common names are universally accepted and rarely change over time.

Study Notes
- Game theory studies mathematical models of strategic interactions among rational agents.
- Applications span economics, political science, biology, and computer science.
Prisoner's Dilemma
- Two suspects, held separately, face a choice to confess or stay silent.
- If one confesses and the other doesn't, the confessor is released, 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) |
- Matrix entries show prison sentences for Suspect A and Suspect B respectively.
Rationality in Game Theory
- Players are assumed to act to maximize their own payoff, given their beliefs.
Nash Equilibrium Defined
- A state where no player benefits from unilaterally changing strategy if others don't.
- In Prisoner's Dilemma, both confessing is the Nash Equilibrium, because each suspect is better off confessing regardless of the other's action
Algorithmic Game Theory (AGT)
- AGT blends game theory and computer science
- It focuses on computational aspects of games.
- Efficient algorithms for finding Nash Equilibria
- Analyzing strategic behavior complexity
- Designing mechanisms to incentivize socially desirable behavior
Key Topics in AGT
- Mechanism Design: rules for achieving desired outcomes even with selfish players.
- Price of Anarchy: measures efficiency degradation from agents behaving selfishly.
- Computational Complexity: analyzes difficulty in computing game-theoretic solutions like Nash equilibrium.
- Learning in Games: focuses on how players learn to play effectively in repeated games, even without knowing other's strategies
Google's Ad Auction: example
- A mechanism design problem where Google maximizes revenue by allocating ad slots.
- Advertisers have different valuations and may be untruthful.
- Google uses a Vickrey-Clarke-Groves (VCG) auction.
- Advertisers bid for slots
- Allocation goes to highest bidders
- Each winner pays the harm caused to other bidders.
- VCG auctions are truthful because bidding true value is always in an advertiser's best interest.
- AGT is a tool for analyzing strategic interactions, improving system design, and increasing efficiency and fairness.
