Improving jump point search

WitrynaThe jump point search algorithm is invented and published by Daniel Harabor and Alban Grastien in 2011. It exploits path symmetry which is manifested as a path (or path segments) which share the same start and goal vertex, have the same length, and are otherwise identical, but differ in the scan order. WitrynaJump Point Search: 又名跳点算法，是在保留A*算法框架的同时，进一步优化了A*算法寻找后继节点的操作。A*是寻找所有当前点的邻居，会有频繁的点集合加入和删除到点集合操作，JPS的优点就是会根据当前点的方向以及当前点周围邻居的特点进行选择某些特殊的点才执行加入和删除到点集合操作。

How does this algorithm work? WitrynaBecause both steps of the algorithm look at, at most, √ n items the algorithm runs in O(√ n) time. This is better than a linear search, but worse than a binary search. The … eaglet accounting

It reduces symmetries in the search procedure by means of graph pruning, eliminating certain nodes in the grid based on assumptions that can be made about the current node's neighbors, as long as certain conditions relating to the grid are satisfied. As a result, the algorithm can consider long "jumps" along straight (horizontal, vertical and diagonal) lines in th…

Witrynathe performance of Jump Point Search. We focus on: (i) more efficient online symmetry breaking that reduces the time spent scanning the grid; (ii) pre-computation strategies for breaking symmetries offline; (iii) more effective online pruning strategies that avoid expanding some jump points. WitrynaJump Point Search (JPS) (Harabor and Grastien 2011) is a recent and very effective technique for identifying and elim- inating path symmetries on-the-fly. JPS can be …
