Evolutive Design of Car Silhouettes

An Interactive Genetic Algorithm system is proposed for designing a car silhouette while involving the style designer in the evaluation process of a population of individuals. This IGA is based on the principle of an indirect encoding of a closed curve genotype using a primary Fourier decomposition. A crossing over operator is proposed for mixing the parents’ genes by a random weighted average into a new child’s genotype. A perceived similarity index between two genotypes is built to check that our IGA is able to converge toward a target individual starting from the genes of an initial population.
