Abstract :
Efficient parallel algorithms for finding an optimum path-shaped or tree-shaped facility with a specified size in a tree network are presented. Four kinds of optimization criteria are considered: minimum eccentricity, maximum eccentricity, minimum distancesum, and maximum distancesum. Eight cases are obtained by combining facility shapes and optimization criteria. Optimal parallel algorithms for finding a minimum/maximum distancesum path were presented by B.C. Tansel et al. (1983). The other six cases are studied here. Two of them can be solved optimally in linear time×processor complexity. For the problem of finding a maximum distancesum tree, the algorithm presented is a polynomial time resolution
