| Abstract;Performance in searching solutions by GA depends on genetic operators and/or their parameters. For comparison of the performance with some genetic operators and/or parameters, we have usually taken the transitions of fitness values. This paper proposes a visualizing method for GA, which can visualize relative distances among chromosomes in search process and give information of not only the performance but also the effects of the genetic operations such as the diversity of chromosomes. This method uses Self-Organizing Map (SOM) for the visualization. This paper shows that the visualized data enables us to interpret the differences in search processes, and to get new information to determine efficient genetic operators and their parameters.
