In order to alleviate the sub-optimal problem of the scheme, caused by the relative independence of task assignment and route planning, in the process of static task planning of multi-UUV, a hybrid optimization algorithm is proposed by the means of combining non dominated sorting genetic algorithm Ⅱ (NSGA-Ⅱ) with dynamic programming algorithm. NSGA-Ⅱ is used as the overall optimization framework to assign tasks to each UUV. Then, the dynamic programming algorithm is applied to each UUV task subset to obtain the task sequence based on the shortest path criterion, which is used evaluate and optimize the task allocation scheme. The simulation results based on typical scenarios show that by embedding dynamic programming algorithm into NSGA-Ⅱ optimization framework and explicitly considering the influence of task execution order on the performance of the scheme in the process of task assignment, the quality of the optimization scheme can be improved and the convergence of NSGA-Ⅱ optimization process can be accelerated.
