Abstract(in English) | This paper proposes a new evolutionary algorithm, hierarchical hillclimbing (HHC), for searching solutions of combinatorial optimization problems. We define hierarchical populations and introduce a new recombination method which is not pair-wise mating. The hierarchical population can maintain the diversity of schemata and make good performance for local searching. The new recombining method make new individuals with probabilities for each bits. And the spurious correlations, which leads the premature convergence, are reduced through recombining of multiple parents. On our simulation, HHC can maintain the competitive schemata and avoid premature convergence through reducing spurious correlations. |
