| Abstract: | From the aspect of solution space, the role of crossover operators is analyzed. For the disadvantage of aimless serarch, an improved genetic algorithm based on oriented crossover is proposed, which can make the offspring individuals evolve towards the target value by optimizing their crossover positions. The evolving probability is very large. The simulation results show that the algorithm can improve greatly the efficiency and precision to find the optimum value. |
