Fitness functions for ant colony paintings

Abstract

A creativity-support tool for the creation of nonphotorealistic renderings of images is described. It employs an evolutionary algorithm that evolves the parameters governing the behavior of ant species, and the paintings are produced by simulating the behavior of these artificial ants. The design of fitness functions, using both behavioral and image features is discussed, emphasizing the rationale and intentions that guided the design. The analysis of the experimental results obtained by using different fitness functions focuses on assessing if they convey the intentions of the fitness function designer.
