1
Q

What is game theory designed to do?

A

Handle questions where the pay-offs of an action depend not only on a players own choice but also of those of others

2
Q

What does game theory depend on?

A

How other people act

3
Q

What is an example of game theory?

A

The prisoners dilemma game

4
Q

What is the conclusion from the prisoners dilemma game?

A

The prisoners should defect (each betrays each other and serves two years)

5
Q

What is the difference between classic and evolutionary game theory?

A

Classic: analytical maths or computer algorithms are applied directly to the payoff matrix to determine optimal strategy

Evolutionary: strategies are encoded as replicators that meet other strategies in populations and compete and reproduce- fitness is based on the pay off matrix

6
Q

What is the concept of the hawk-dove game?

A

Hawks behave aggressively until injured or the contest is won

The doves display and retreat if the component behaves aggressively

7
Q

From the payoff matrix what is the optimal strategy in a basic hawk-Dove game?

A

There should be a mixed population of hawks and doves

8
Q

What is the criticism of game theory?

A

Rationality is assumed- they always make good decisions

9
Q

How can the evolution of behaviour with cognitive constraints be modelled?

A

Using artificial neural networks

10
Q

What is the perceptron?

A

A fundamental subunit of the neural network that passes information

11
Q

What are artificial neural networks?

A

Simply lots of perceptrons joined together and passing information between each other

12
Q

What is the confusion effect?

A

If there is more prey it is harder for the predator to focus on an individual and they get confused
