WebMany artificial intelligence problems are NP-complete ones. To decrease the needed time of such a problem solving a method of extraction of sub-formulas characterizing the common features of objects under consideration is suggested. This method is based on the offered by the author notion of partial deduction. Repeated application of this procedure allows to … WebM. R. Garey and D. S. Johnson.

No, it's not NP-hard; you can use a shortest path algorithm (such as Bellman-Ford) to solve it in polynomial time by negating your edge lengths. Note that it is likely that the longest path will be infinite, particularly when all edge weights are non-negative. Shortest simple path in a graph without negative cycles is not NP-hard. high intensity industrial uv lights
