1977 A Note on Spira's Algorithm for the All-Pairs Shortest-Path Problem
abstract
We correct some errors in Spira’s algorithm for the all-pairs shortest-path problem, and empirically compare his algorithm (with two distinct sorting, routines) to Dijkstra’s procedure. The results show that Spira’s algorithm is only efficient for “large” networks. Furthermore, it is seen that the asymptotic number of additions and comparisons required by two algorithms may be a very poor indicator of their relative running times.
