For the problem of finding the shortest paths from a prescribed vertex to the other vertices in a given network with nonnegative arc lengths, we investigate practical efficiencies of typical existing algorithms, i.e., the label-correcting method with a FIFO and that of a two-way sequence, and the label-setting method with a heap and that with a 1- or 2-level bucket system. We propose also a new method with a variable bucket system and compare it with those existing methods. Among the existing… CONTINUE READING
