Limited discrepancy search is an eeective algorithm for problems where only part of a tree has to be searched to nd a solution, or the problem size prohibits an exhaustive search. We presented an improved version of the algorithm that reduces its time complexity from O(d+2 2 2 d) to O(2 d) for searching a complete binary tree of uniform depth d. In practice, however, the improvement is much less due to pruning of the tree, and we measured a factor of six improvement on trees of depth 35. While… CONTINUE READING
