We consider dual approaches for the Shortest Path Tree problem. After a brief introduction to the problem, we review the most important dual algorithms which have been described in the literature for its solution and propose a new family of dual ascent algorithms. In these algorithms, ''local'' and

The Capacitated Shortest Spanning Tree Problem consists of determining a shortest spanning tree in a vertex weighted graph such that the weight of every subtree linked to the root by an edge does not exceed a prescribed capacity. We propose a tabu search heuristic for this problem, as well as dynami
We present a simple parallel algorithm for the single-source shortest path problem in planar digraphs with nonnegative real edge weights. The algorithm runs on the EREW PRAM model of parallel computation in O((n 2= +n 1&= ) log n) time, performing O(n 1+= log n) work for any 0<=<1Γ2. The strength of
