On a nonbasic dual method for the transportation problem,roblems in a digraph with at most . nodes and nonnegative arcs. This approach was first proposed by Hoffman and Markowitz and successively improved by Lagemann; here the method is revisited using recent results in subgradient and network flow optimization techniques. At each iteration of the solutio

Tailoring Benders decomposition for uncapacitated network design,his paper studies the application and acceleration of Benders decomposition for uncapacitated models from this problem class and illustrates the potential flexibility of the Benders solution strategy. In particular, it (i) shows that several lower bounding inequalities from the literature can be der

An algorithm for the Rural Postman problem on a directed graph, is ‘required’ to be traversed at minimum cost. If this subset does not form a weakly connected graph but forms a number of disconnected components the problem is NP-Complete, and is also a generalization of the asymmetric Travelling Salesman Problem. In this paper we present a branch and bound algo

Common aspects of several network flow algorithms,ic or nonbasic and incremental or nonincremental. The distinction between primal and dual degenerate pivots sheds some light on complexity and degeneracy issues. A detailed presentation of this material is given in Siedersleben (1983).
