WebRectangular Symmetry Reduction (RSR) is an A* pathfinding variant. During the frontier expansion step, regular A* may only add adjacent nodes -- after all, it doesn't know anything about the nature of the terrain data. On the other hand, RSR knows that it's in a rectangle, so it can discount the entire interior of the rectangle -- the point ... WebJun 29, 2011 · The new algorithm, Rectangular Symmetry Reduction (RSR), can speed up A* search by up to 38 times on a range of uniform cost maps taken from the literature. In addition to being fast and optimal, RSR requires no significant extra memory and is largely orthogonal all existing speedup techniques. When compared to the state of the art, RSR …
