Evolutionary Creativity

Abstract

When Darwin published his theories about evolution, he presented two key mechanisms responsible for the evolution (natural selection and sexual selection). While the natural selection has widely accepted by the scienti c community, the sexual selection has highly criticised and so it was forgotten over time. It was only nearly a century later, that the sexual selection began to be acknowledged, mainly due the researches of Fisher and Zahavi. In the last decades, other matter that has intrigued the scienti c community is the reasons that lead an individual to join a herd and how to describe the movements observed in these herds. Some authors, among which Reynolds, suggest that the ocking behaviour emerges through simple motion rules. Afterwards, hybrid algorithms combining the ideas from evolution and motion of ocks were presented. In such algorithms, the motion rules evolve over the time. Inspired in these algorithms, in this dissertation is proposed a new algorithm, which inserts in these hybrid models the ideas from sexual selection, in particular mate choice. In the end, the emergence of a ocking behaviour is expected and the e ects of using mate choice instead of the traditional approaches are analysed.
