摘要:

基于采样的算法通过在搜索空间中生成随机样本并递增地生长连通图或树来解决路径规划问题。传统上,这些算法中使用的采样策略偏向于探索以获取关于搜索空间的信息。相比之下,这项工作提出了一个基于优化的过程,生成新的样本,以提高成本来的价值的顶点在一个街区。该算法的应用程序增加了一个剥削偏置采样和结果在一个更快的收敛到最优解相比,其他国家的最先进的采样技术。这是证明使用基准实验进行fora各种更高的维度机器人规划任务。

英文摘要:

Sampling-based algorithms solve the path planning problem by generating random samples in the search-space and incrementally growing a connectivity graph or a tree. Conventionally, the sampling strategy used in these algorithms is biased towards exploration to acquire information about the search-space. In contrast, this work proposes an optimization-based procedure that generates new samples to improve the cost-to-come value of vertices in a neighborhood. The application of proposed algorithm adds an exploitative-bias to sampling and results in a faster convergence to the optimal solution compared to other state-of-the-art sampling techniques. This is demonstrated using benchmarking experiments performed fora variety of higher dimensional robotic planning tasks.
