Summary:In the area of Interactive Evolutionary Computation (IEC), some previous studies have already proposed a method for creating music melody. However, in these methods, user's concrete intention or Kansei seems not to be reflected to the created melodies. This study focuses on this point: reflection of user's concrete intention and Kansei in IEC. While most of conventional IEC approaches accepted only user's evaluation by scoring or comparing solution candidates, the proposed method accepts user's operation for solution candidates as user's intervention. To investigate the proposed method for creation of music melody, listening experiments were conducted. In the experiment, the subjects listened to music melody created from the IEC system based on the proposed method. With the system, the subjects can control key of music note in melody by themselves when they wanted to change the melody. As result of experiment, the mean fitness value gradually increased in accordance with progress of generation, and significant differences between the first generation and other generations were observed. The experiment also investigated the efficacy of the user's intervention.
