Subgoal graphs
Websubgoal graphs by identifying subgoals and checking direct-h-reachability in the preprocessing stage. Compared with the original map, the subgoal graph abstracts the information of key points, so as to reduce the search space. The direct-h-reachability ensures that any shortest paths between adjacent Web7 Jun 2015 · Simple Subgoal Graphs are constructed from grids by placing subgoals at the corners of obstacles and connecting them. They are analogous to visibility graphs for …

Web10 Jun 2013 · Subgoal graphs for optimal pathfinding in eight-neighbor grids Pages 224–232 ABSTRACT Grids are often used to represent maps in video games. In this … WebN-Level Subgoal Graphs prune vertices using shortest paths, while ENLSVGs prune edges using taut paths. We also introduce Line-of-Sight Scans, a fast algorithm for querying visible neighbours of a vertex in the grid. This replaces Line-of-Sight Checks for building the Visibility Graph and inserting the start and goal points into the graph.

Variations of this method use two-level subgoal graphs and two-level subgoal graphs with pairwise distances. In a square grid, there is a limit of eight neighbors.
WebSimple Subgoal Graphs (SSGs) was a non-dominated optimal path-planning algorithm in the Grid-based Path Planning Competitions 2012 and 2013. They are constructed from grids by placing subgoals at the convex corners of obstacles and connecting pairs of subgoals that are direct-h-reachable. Web7 Feb 2024 · Learning to reach long-horizon goals in spatial traversal tasks is a significant challenge for autonomous agents. Recent subgoal graph-based planning methods address this challenge by decomposing a goal into a sequence of shorter-horizon subgoals. These methods, however, use arbitrary heuristics for sampling or discovering subgoals, which …
