借用著名的LPA*算法的思路,本文提出了一种基于快速探索随机图(RRG)的新的增量采样运动规划算法。
它还保证了以初始状态为根的构造生成树包含有可能成为最优解一部分的顶点的最低成本路径信息。这意味着,如果当前图中有一些顶点已经在目标区域内,那么就很容易计算出可能的最佳解决方案。
本文提出了一种新的基于增量采样的算法,用RRT#表示,它为解决运动规划问题提供了渐进的最优解。通过纳入树中所有当前顶点的静止性信息,我们可以对潜在路径的最优值进行更明智的估计,这导致初始收敛率优于RRT*算法。本文的工作可以在几个方向上进行扩展。首先,由于RRT#算法将顶点集分解为 "有希望的 "和 “无希望的”,可以开发更聪明的采样策略来利用这些信息。
此外,该算法的并行版本 该算法的并行版本可以通过将Extend和Replan程序作为独立的线程来实现。最后,开发步骤可以只在当前树上添加了几个新顶点后定期执行。这些扩展是正在进行的工作的一部分
