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. WitrynaIn 2011, Harabor and Grastien introduced Jump Point Search (JPS) that achieves up to a 10x speed improvement over A* on uniform cost grids. In the last year, an additional 10x speed improvement to JPS, called JPS+ was independently developed by Steve Rabin as well as Harabor and Grastien. This improved algorithm is over 100x faster …

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. How does this algorithm work? 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… WitrynaImproving Jump Point Search.
