The complete thesis is available as a compressed postscript file. You have a choice of either full size , or two-up printing if you want to save paper. The bibliography can be downloaded separately if needed. Evolutionary simulation models are advocated as a way of testing the coherence of a given theory. The second model is concerned with communication during aggressive interactions.
Many animals use signals to settle contests, thus avoiding the costs associated with fighting.
The simulation, which features continuous-time perception of the opponent's strategy, is an attempt to settle the question. The third model deals with sexual signalling, i.e., elaborate displays that are designed to persuade members of the opposite sex to mate. The results clarify the question of whether such displays are the pointless result of runaway sexual selection, or whether they function as honest and costly indicators of genetic quality. Future directions for simulation work are discussed. Last modified October 2000.
