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, [1] 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 ...

May 5, 2013 · You can play with A* and JPS here. Click and drag anywhere to add obstacles, drag the green (start) and red (goal) nodes to move them, and click the “Find Path” button to find a best path.

Jump Point Search (JPS) is a specialized, optimal algorithm used for traversing uniform-cost grid environments. The algorithm is ideal for traversing 8-way grid-based map representations, though it can be customized to accommodate other types of grids.

Apr 26, 2017 · I know that A* is better than Dijkstra's algorithm because it takes heuristic values into account, but from A* and Jump Point search which is the most efficient algorithm for finding the shortest path in an environment with obstacles? and what are the differences?

Oct 31, 2015 · This article explains the Jump Point Search algorithm they presented, a pathfinding algorithm that is faster than A* for uniform cost grids that occur often in games.

Jun 21, 2022 · The JPS algorithm is a pathfinding algorithm that uses pruned neighbor rules as the search direction of nodes and the position of forced neighbors as the judgment of jump points.

The basic idea is that JPS allows to throw away many candidate paths early, therefore reducing the amount of computations required. In many maps, multiple paths with the same cost lead to same destination, such as a game map with large open areas. JSP allows pruning those paths. An in-depth explanation can be found here.

In this research I will cover the optimized method of A* pathfinding algorithm, the Jump Point Search algorithm (JPS), which can speed up A* by orders of magnitude.

(JPS) is a recent algorithm for improving path planning on uniform cost grids. breaks down JPS into several pieces that can be applied or modified independently.

Apr 10, 2015 · Boundary lookup jump point search (BL–JPS) is a modification that improves the speed of JPS. BL–JPS records the positions of obstacle boundaries and uses these via direct lookup to eliminate much of the iteration involved in searching for …
