WitrynaWe 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. 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.

Witryna10 maj 2014 · A new and effective method to identify jump points quickly through bit operations at a single time and a symmetry-breaking heuristic function to pruning … 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… WitrynaWhile JPS expands far fewer nodes, note that it generates states that A* does not. This because it follows the canonical ordering to the edge of the map while looking for … inward curve near kidney

WitrynaActually, if you look at the definition of 45-degree route, it is always possible to transform a path with 45-degree route into a path without 45-degree turn. And it's also optimal (you can easily prove it by contradiction). So, the simplest way is to run the jump point search and then transform it into orthogonal route. WitrynaThe basic idea is that JPS allows to throw away many candidate paths early, therefore reducing the amount of computations required.
