Informed Search for Regular Path Query Reachability

Diego Rivera Correa, Laurent Bindschaedler · 9th Joint Workshop on Graph Data Management Experiences & Systems and Network Data Analytics (GRADES-NDA), 2026

Studies heuristic-guided (greedy best-first / A*) search for evaluating Regular Path Query reachability over the product graph, finding that the search regime dominates heuristic choice and that DFS remains hard to beat for Boolean reachability.
