A novel backward search system has been developed in accordance with the theoretical foundations provided by narrowing.
Even though the foundations of the analysis are the rules described in Section 2, they are automatically transformed in order to apply the backward search, which in turn is not implemented in the core distribution of Maude and hence requires further modifications to be used.
Using the planning graph and the lists of mutually exclusive facts and actions, TGP now conducts a backward search through the metaproblem space.
TGP performs a backward search on the planning graph that remains unchanged during each search episode.
He finds the explanation not in the onward march of technology but in their backward search

Webcrawler http://www.webcrawler.com This search engine has a convenient "backward search" to find out who has linked to you.
Overall, the planner FF, based on similar ideas, did better and, in certain cases, significantly better primarily because of three factors: (1) the search direction (forward search appears to be more robust than backward search
), (2) a heuristic more accurate than [h.sub.add] (the only heuristic used by HSP2.0 in the forward direction), and (3) a good rule for quickly discarding nodes without computing their heuristic values.
WebCrawler has another feature that is useful to users with their own home pages: a backward search
