Tournament Interactive Genetic Algorithm (T-IGA) and Paired Comparison-based Interactive Differential Evolution (PC-IDE) are applied to the design of stained glass windows and the two algorithms with variable length genotype are compared in a context of interactive evolutionary computation. For both methods, stained glass windows are represented by colored 2D Voronoi diagrams, and a specific phenotypic crossover operator allows offspring to inherit visual features from both parents. The two algorithms have been evaluated by two professional stained-glass artists whom use them to create original designs in a controlled experimental setting. The results indicate superiority of PC-IDE, thus confirming previous theoretical results.
