Branch-and-price-and-cut for large-scale multicommodity capacitated fixed-charge network design

open access: yesEURO Journal on Computational Optimization, 2014
We present a branch-and-price-and-cut algorithm for solving large-scale instances of the multicommodity capacitated fixed-charge network design problem.

Compact ILP formulations for the routing and wavelength assignment problem in the design of optical transport networks with regenerators

open access: yesEURO Journal on Computational Optimization, 2016
This paper addresses two variants of the routing and wavelength assignment problem arising in the context of optical transport networks. In both variants, we address the case where the physical coverage of the fiber network is such that regenerators, to ...

Ringo: Interactive Graph Analytics on Big-Memory Machines [PDF]

open access: yes, 2015
We present Ringo, a system for analysis of large graphs. Graphs provide a way to represent and analyze systems of interacting objects (people, proteins, webpages) with edges between the objects denoting interactions (friendships, physical interactions ...

Chemical concrete machine [PDF]

open access: yes, 2013
The chemical concrete machine is a graph rewriting system which uses only local moves (rewrites), seen as chemical reactions involving molecules which are graphs made up by 4 trivalent nodes.

Finding and counting vertex-colored subtrees [PDF]

open access: yes, 2010
The problems studied in this article originate from the Graph Motif problem introduced by Lacroix et al. in the context of biological networks. The problem is to decide if a vertex-colored graph has a connected subgraph whose colors equal a given ...

Bias estimation in sensor networks [PDF]

open access: yes, 2019
This paper investigates the problem of estimating biases affecting relative state measurements in a sensor network. Each sensor measures the relative states of its neighbors and this measurement is corrupted by a constant bias.

Complex networks and public funding: the case of the 2007-2013 Italian program [PDF]

open access: yes, 2015
In this paper we apply techniques of complex network analysis to data sources representing public funding programs and discuss the importance of the considered indicators for program evaluation.

Optimal curing policy for epidemic spreading over a community network with heterogeneous population

open access: yes, 2017
The design of an efficient curing policy, able to stem an epidemic process at an affordable cost, has to account for the structure of the population contact network supporting the contagious process.

Distributed Basis Pursuit [PDF]

open access: yes, 2012
We propose a distributed algorithm for solving the optimization problem Basis Pursuit (BP). BP finds the least L1-norm solution of the underdetermined linear system Ax = b and is used, for example, in compressed sensing for reconstruction.
