"WitrynaFrom visual representation, Jump Point Search seems to be making a lot of random guesses (probably very intelligent ones) at finding the path (from the block selection at least), but I haven't yet found a test case where this algorithm yielded worse results than A* and Dijkstra.

Witryna10 maj 2014 · We give online and offline optimisation techniques to improve the performance of Jump Point Search (JPS): a recent and very effective symmetry-breaking algorithm that speeds up pathfinding in computer games. In computer science, jump point search (JPS) is an optimization to the A* search algorithm for uniform-cost grids. 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 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. WitrynaTo address the problems of the traditional A∗ algorithm in solving paths with many expansion nodes, high memory overhead, low operation efficiency, and many path corners, this paper improved the traditional A∗ algorithm by combining jump point search strategy and adaptive arc optimization strategy.
