โฆ Synopsis
This paper presents a faster algorithm for the M-convex submodular How problem, which is a generalization of the minimum-cost How problem with an M-convex cost function for the How-boundary, where an M-convex function is a nonlinear nonseparable cliserete convex function on integer points. The algorithm extends the capacity sealing approach lor the submodular How problem by Fleischer. Iwata and MeCormiek (2002) with the aid of a novel technique of changing the potential by solving maximum submodular How problems.

This paper presents a cost-scaling algorithm for minimum cost O-l submodular flows. The algorithm works by splitting the arc costs approximately and maintaining an optimal submodular pseudoflow with respect to the split costs obtained by a greedy algorithm. Each scaling phase of the algorithm is a h
## Abstract The constrained maximum flow problem is to send the maximum possible flow from a source node s to a sink node t in a directed network subject to a budget constraint that the cost of flow is no more than __D__. In this paper, we consider two versions of this problem: (i) when the cost of
