BioNB 2210: Lecture 26 Oct. 26, 2011 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. Hawk Dove Bourgeois Assessor Hawk -1 2 0.5 -1 Dove 0 1 0.5 0.5 Bourgeois - 0.5 1.5 1.0 - 0.25 Assessor 1 1.5 1.25 1 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
