The GRT Planner
This article presents the GRT planner, a forward heuristic state-space planner, and comments on the results obtained from the Fifth International Conference on Artificial Intelligence Planning and Scheduling (AIPS'00) planning competition. The grt planner works in two phases. In the preprocessing phase, it estimates the distances between the facts and the goals of the problem. During the search phase, the estimates are used to guide a forward-directed search. grt participated in the strips track of the competition and showed promising results. Although it did not gain any prize, it gave us good prospects for the future.
