Crossover Method for Interactive Genetic Algorithms to Estimate Multimodal Preferences

Figure 19

Mean of the evaluation values of population in each generation. The results of the proposed method are depicted by the solid red lines and those of the conventional method by the dotted blue lines. The number of landscapes is the number of trials by each method and means the number of samples.

(a) Mean of the evaluation values estimated from the search results obtained from the 9 unimodal landscapes

(b) Mean of the evaluation values estimated from the search results obtained from the 27 multimodal landscapes
