The budgeted minimum cost flow problem with unit upgrading cost

Networks, 2016
The budgeted minimum cost flow problem (BMCF(K)) with unit upgrading costs extends the classical minimum cost flow problem by allowing one to reduce the cost of at most K arcs. In this article, we consider complexity and algorithms for the special case of an uncapacitated network with just one source.

A bi-objective column generation algorithm for the multi-commodity minimum cost flow problem [PDF]

open access: yesEuropean Journal of Operational Research, 2015
We present a column generation algorithm for solving the bi-objective multi-commodity minimum cost flow problem. This method is based on the bi-objective simplex method and Dantzig–Wolfe decomposition.

Multi-player minimum cost flow problems with nonconvex costs and integer flows

2016 IEEE 55th Conference on Decision and Control (CDC), 2016
In this paper we consider a variant of the well known minimum cost flow problem in a directed network with nonconvex costs and integer flows. We formulate the problem in a multi-player setup, whereby we associate one player with each arc of the network.

Solving minimum-cost flow problems by successive approximation

Proceedings of the nineteenth annual ACM conference on Theory of computing - STOC '87, 1987
We introduce a framework for solving minimum-cost flow problems. Our approach measures the quality of a solution by the amount that the complementary slackness conditions are violated. We show how to extend techniques developed for the maximum flow problem to improve the quality of a solution. This framework allows us to achieve O(min(n3, n5/3 m2/3, nm

Minimum-Cost Flow Problems

1991
The minimum-cost flow problem defined on a directed graph G = (V,A) is that of finding a feasible flow of minimum cost. In addition to the maximum flow problem, each arc (i,j) e A has associated an integer c(i,j) referred to as cost per unit of flow. Let b: V ↦ R be the demand-supply vector, where b(j) 0 if j is a destination vertex, and b(j) = 0 for

Minimum cost time-varying network flow problems

Optimization Methods and Software, 2010
This paper deals with a general minimum cost dynamic flow problem in a discrete time model with time-varying transit times, transit costs, transit capacities, storage costs, and storage capacities. For this problem, an algorithm of time complexity O(V nT(n+T)) is presented, where V is an upper bound on the total supply, n is the number of nodes, and T ...

Possibilistic Minimum-cost Flow Problem

2001
To illustrate the applications of the proposed fuzzy approaches, the minimum-cost flow (MCF) problem was investigated and several examples were solved. Minimum-cost flow problem is a general form of network flow problem, whose aim is to find the least cost of shipments of commodities through capacitated network in order to satisfy demands at certain ...
