(Attractiveness vs. Efficiency)
3 Fitness
Genetic algorithm-based systems for optimizing motor control in physically-based articulated figures typically update a population of genotypes in discrete generations, and use a pre-defined fitness function to control reproduction. This simulation places each organism of the population in a common spatial domain and allows mate selection to be local and autonomous. It does not use a pre-defined fitness function: fitness is instead considered as a property of the simulation: defined as the rate at which the population reproduces. Now, what is required for a higher reproductive rate in the population is a set of necessary emergent properties in individuals, such as: swimming quickly and efficiently towards mates or food; turning efficiently; and, of course, being attractive.
