Abstract: Multi-Robot Coalition Formation is an important cooperative method,which is a complicated combinatorial optimization problem.In this paper,an improved quantum genetic algorithm is proposed,where a novel “the islands model based on information positive feedback” and a strategy for updating quantum gate using the evolutionary equation are employed to avoid the premature convergence.The results of simulation experiments show that this algorithm is valid and superior to other related methods as far as the stability and speed of convergence.

摘要: 联盟是多机器人之间一种重要的合作方法,如何生成面向某个任务的最优联盟是一个复杂的组合优化问题。引入量子遗传算法来解决这一问题,在求解过程中引入“基于信息正反馈的岛屿模型”对量子遗传算法进行改进,并采用进化方程对量子门进行更新,使其不再易于陷入局部极值。仿真实验结果表明,该算法在解的质量和收敛速度上优于目前同类算法。
