Approximation algorithms for the unsplittable flow problem

A Chakrabarti, C Chekuri, A Gupta, A Kumar - Algorithmica, 2007 - Springer
We present approximation algorithms for the unsplittable flow problem (UFP) in undirected
graphs. As is standard in this line of research, we assume that the maximum demand is at …

Improved bounds for the unsplittable flow problem

P Kolman, C Scheideler - Journal of Algorithms, 2006 - Elsevier
In this paper we consider the unsplittable flow problem (UFP): given a directed or undirected
network G=(V, E) with edge capacities and a set of terminal pairs (or requests) with …

Approximation algorithms for the unsplittable flow problem

A Chakrabarti, C Chekuri, A Gupta, A Kumar - … Algorithms for Combinatorial …, 2002 - Springer
We present approximation algorithms for the unsplittable flow problem (UFP) on undirected
graphs. As is standard in this line of research, we assume that the maximum demand is at …

Combinatorial algorithms for the unsplittable flow problem

Y Azar, O Regev - Algorithmica, 2006 - Springer
We provide combinatorial algorithms for the unsplittable flow problem (UFP) that either
match or improve the previously best results. In the UFP we are given a (possibly directed) …

An approximation algorithm for the disjoint paths problem in even-degree planar graphs

J Kleinberg - 46th Annual IEEE Symposium on Foundations of …, 2005 - ieeexplore.ieee.org
In joint work with Eva Tardos in 1995, we asked whether it was possible to obtain a
polynomial-time, polylogarithmic approximation algorithm for the disjoint paths problem in …

Edge disjoint paths in moderately connected graphs

S Rao, S Zhou - SIAM Journal on Computing, 2010 - SIAM
We study the edge disjoint paths (EDP) problem in undirected graphs: Given a graph G with
n nodes and a set T of pairs of terminals, connect as many terminal pairs as possible using …

Approximation algorithms for edge-disjoint paths and unsplittable flow

T Erlebach - Efficient Approximation and Online Algorithms: Recent …, 2006 - Springer
In the maximum edge-disjoint paths problem (MEDP) the input consists of a graph and a set
of requests (pairs of vertices), and the goal is to connect as many requests as possible along …

LS (Graph): a constraint-based local search for constraint optimization on trees and paths

QD Pham, Y Deville, P Van Hentenryck - Constraints, 2012 - Springer
Constrained optimum tree (COT) and constrained optimum path (COP) problems arise in
many real-life applications and are ubiquitous in communication networks. They have been …

Finding edge-disjoint paths in networks: An ant colony optimization algorithm

MJ Blesa, C Blum - Journal of Mathematical Modelling and Algorithms, 2007 - Springer
One of the basic operations in communication networks consists in establishing routes for
connection requests between physically separated network nodes. In many situations, either …
