Solving the 8-Puzzle using A* Heuristic Search

www.cse.iitk.ac.in

A non-admissible heuristic may overestimate the cost of reaching the goal. It may or may not result in an optimal solution. However, the advantage is that sometimes, a non-admissible heuristic expands much fewer nodes. Thus, the total cost (= search cost + path cost) may actually be lower than an optimal solution using an admissible heuristic.
