Modelling The Evolution Of Animal Behaviour Flashcards
What is game theory designed to do?
Handle questions where the pay-offs of an action depend not only on a players own choice but also of those of others
What does game theory depend on?
How other people act
What is an example of game theory?
The prisoners dilemma game
What is the conclusion from the prisoners dilemma game?
The prisoners should defect (each betrays each other and serves two years)
What is the difference between classic and evolutionary game theory?
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
What is the concept of the hawk-dove game?
Hawks behave aggressively until injured or the contest is won
The doves display and retreat if the component behaves aggressively
From the payoff matrix what is the optimal strategy in a basic hawk-Dove game?
There should be a mixed population of hawks and doves
What is the criticism of game theory?
Rationality is assumed- they always make good decisions
How can the evolution of behaviour with cognitive constraints be modelled?
Using artificial neural networks
What is the perceptron?
A fundamental subunit of the neural network that passes information
What are artificial neural networks?
Simply lots of perceptrons joined together and passing information between each other
What is the confusion effect?
If there is more prey it is harder for the predator to focus on an individual and they get confused
