Abstract
The use of approximate algorithms in aiding heuristic search is explored. Approximate algorithms are coupled with algorithm A to generate an algorithm BFPR which maintains provably good quality of solutions. Experiments were performed with Euclidean Traveling Salesman problem and with the problem of Scheduling Independent Tasks. It is found that the algorithm expands considerably fewer number of nodes and yet very often produces optimal solutions.
