Minimum cost flow algorithms for series-parallel networks
نویسندگان
چکیده
It is shown that an acyclic multigraph with a single source and a single sink is series-parallel if and only if for arbitrary linear cost functions and arbitrary capacities the corresponding minimum cost flow problem can be solved by a greedy algorithm. Furthermore, for networks of this type with m edges and n vertices, two O(mn + m log m)-algorithms are presented. One of them is based on the greedy scheme.

The budgeted minimum cost flow problem with unit upgrading cost
The budgeted minimum cost flow problem (BMCF(K)) with unit upgrading costs extends the classical minimum cost flow problem by allowing to reduce the cost of at most K arcs. In this paper, we consider complexity and algorithms for the special case of an uncapacitated network with just one source. By a reduction from 3-SAT we prove strong NP-completeness and inapproximability, even on directed ac...
متن کاملAn Efficient Parallel Algorithm for Min-Cost Flow on Directed Series-Parallel Networks
We consider the problem of nding the minimum cost of a feasible ow in directed series-parallel networks. We allow real-valued lower and upper bounds for the ows on edges. While strongly polynomial-time algorithms are known for this problem on arbitrary networks, it is known to be \hard" for parallelization. We develop, for the rst time, an eecient NC algorithm to solve the min-cost ow problem o...
متن کاملScheduling of Multiple Autonomous Guided Vehicles for an Assembly Line Using Minimum Cost Network Flow
This paper proposed a parallel automated assembly line system to produce multiple products having multiple autonomous guided vehicles (AGVs). Several assembly lines are configured to produce multiple products in which the technologies of machines are shared among the assembly lines when required. The transportation between the stations in an assembly line (intra assembly line) and among station...
متن کاملSublinear-Time Parallel Algorithms for Matching and Related Problems
This paper presents the first sublinear-time deterministic parallel algorithms fix bipartite matching and several related problems, including maximal node-disjoint paths, depth-first search, and flows in zero-one networks. Our results are based on a better understanding of the combinatorial structure of the above problems, which leads to new algorithmic techniques. In particular, we show how to...
متن کاملA Novel Experimental Analysis of the Minimum Cost Flow Problem
In the GA approach the parameters that influence its performance include population size, crossover rate and mutation rate. Genetic algorithms are suitable for traversing large search spaces since they can do this relatively fast and because the mutation operator diverts the method away from local optima, which will tend to become more common as the search space increases in size. GA’s are base...
