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. 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 … raymon raymongrace.us
