Lecture 26:
Modeling Conflict:
Game Theory 2
Professor H. Kern Reeve
Learning Objectives
1.
To understand the Producer-Scrounger game.
2.
To understand how asymmetric games work, including the Parental Care game.
Goal:
To continue to apply game theoretic techniques to the evolutionary analysis of
producer-scrounger foraging games and to asymmetric games including the
parental care game.
1. The Assessor Strategy
What if we added a new strategy to the Hawk-Dove game: the Assessor strategy.
It
assesses the relative strength of its opponent and behaves like a Hawk if it perceives itself
to be stronger and like a Dove if it perceives itself to be weaker.
Let V = 2 and C = 4, as
before.

2. The Producer-Scrounger Game
Imagine a new game in which Producers search for food, whereas Scroungers lazily wait
until Producers find food and then attempt to take some of it.
A Scrounger paired with a
