Subgoal graphs
Web8 Apr 2015 · SUB_GOALs identified with pre-searching from basic A* at break points and Subgoal Graphs at corners of obstacles are added to SUB_TABLE to expedite the final … 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
