基于ISMA的多点遍历路径规划方法

针对移动机器人在遍历多目标点的路径规划中存在路径较长且不平滑等问题,本文提出一种基于ISMA的多点遍历路径规划方法。首先,结合Singer映射和小孔成像反向学习策略改进标准黏菌算法(SMA);然后初步构建地图,使用ISMA规划路径,以确定三角网格最大边长的最优值;最后,基于三角网格最大边长的最优值重新构建三角网格地图,使用ISMA生成路径,并通过B样条函数对路径进行光滑处理,提升路径平滑度。基准函数测试结果表明,ISMA收敛速度更快,寻优精度更高。三角网格地图上的路径规划实验表明：ISMA规划的路径长度和平滑度明显优于SMA、SSA和WOA,与SMA、SSA和WOA相比,在较复杂的场景中ISMA生成路径的长度依次减少了6.31%、18.76%和19.74%,验证了ISMA方法的有效性。

Mobile robot multi-goal path planning using improved slime mould algorithm

Aiming at the problems of long and unsmooth paths in the path planning of mobile robots traversing multiple target points, thispaper proposes a multi-point traversal path planning method based on improved SMA. Firstly, the standard slime mold algorithm (SMA)is improved by combining Singer mapping and small hole imaging reverse learning strategy. Then, the map is preliminarily constructed,and the improved SMA is used to plan the path to determine the optimal value of the maximum side length of the triangular mesh.Finally, the triangular grid map is reconstructed based on the optimal value of the maximum edge length of the triangular mesh, theimproved SMA is used to generate the path, and the path is smoothed by the B spline function to improve the smoothness of the path.The benchmark function test results show that the improved SMA converges faster and has higher optimization accuracy. Path planningexperiments on triangular grid maps show that the path length and smoothness of improved SMA planning are significantly better thanthose of SMA, SSA and WOA, and compared with SMA, SSA and WOA, the length of the improved SMA generated path in complexscene is reduced by 6. 31%, 18. 76% and 19. 74%, which verifies the effectiveness of the improved SMA method.
