This paper describes a route planner that enables an to selectively complete part of the predetermined tasks in the operating ocean area when the local path cost is stochastic. The problem is formulated as a variant of the . Based on the (GA), we propose the greedy strategy based GA (GGA) which includes a novel rebirth operator that maps infeasible individuals into the feasible solution space during evolution to improve the efficiency of the optimization, and use a differential evolution planner for providing the deterministic local path cost. The uncertainty of the local path cost comes from unpredictable obstacles, measurement error, and trajectory tracking error. To improve the robustness of the planner in an uncertain environment, a sampling strategy for path evaluation is designed, and the cost of a certain route is obtained by multiple sampling from the probability density functions of local paths. Monte Carlo simulations are used to verify the superiority and effectiveness of the planner. The promising simulation results show that the proposed GGA outperforms its counterparts by 4.7%–24.6% in terms of total profit, and the sampling-based GGA route planner (S-GGARP) improves the average profit by 5.5% compared to the GGA route planner (GGARP).

The path-planning algorithm of AUV in 3D seabed environment is studied. For 3D environment, the optimal paths are classified into three different types. The optimal paths of each type are obtained flexibly by using genetic algorithm, especially the incorporating of problem-specific knowledge and penalty function. Simulation results show the feasibility and reliability of the path-planning algorithm, which has considerable value on the safe navigation of AUV in seabed environment.
