Flows on few paths: Algorithms and lower bounds

M Martens, M Skutella - Networks: An International Journal, 2006 - Wiley Online Library
The classical network flow theory allows decomposition of flow into several chunks of
arbitrary sizes traveling through the network on different paths. In the first part of this article …

Constructing disjoint paths for secure communication

A Bagchi, A Chaudhary, MT Goodrich, S Xu - Distributed Computing: 17th …, 2003 - Springer
We propose a bandwidth-efficient algorithmic solution for perfectly-secure communication in
the absence of secure infrastructure. Our solution involves connecting vertex pairs by a set …

[PDF][PDF] Using branch-and-price to solve multicommodity k-splittable flow problems

J Truffot, C Duhamel, P Mahey - Proceedings of international network …, 2005 - truffot.fr
In this paper we present a column generation model and a branch-and-price algorithm for a
multicommodity k-splittable flow problem. The k-splittable flow is an extension of the …
