| Details | In this study, we propose to use correlation coefficients of search points in order to detect such distribution. The correlation coefficients between decision variables can be obtained from the search points. The highly correlated variables (genes) are grouped and the grouped genes are crossed (or not crossed) simultaneously. However, if only GBX is used as a crossover operation, the diversity of the search points tends to be lost rapidly. In order to keep the diversity, we propose to adjust the probability of applying GBX adaptively. In this study, GBX and adaptive adjustment of the probability of applying GBX is introduced to JADE where JADE is extended by group learning. |
