A new polynomially bounded shortest path algorithm. (English) Zbl 0578.90089

Summary: This paper develops a new polynomially bounded shortest path algorithm, called the partitioning shortest path (PSP) algorithm, for finding the shortest path from one node to all other nodes in a network containing no cycles with negative lengths. This new algorithm includes as variants the label setting algorithm, many of the label correcting algorithms, and the apparently computationally superior threshold algorithm.
