Evaluating performance of image segmentation criteria and techniques

open access: yesEURO Journal on Computational Optimization, 2013
The image segmentation problem is to delineate, or segment, a salient feature in an image. As such, this is a bipartition problem with the goal of separating the foreground from the background. An NP-hard optimization problem, the Normalized Cut problem,

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 ...

Road network emergency accessibility planning after a major earthquake

open access: yesEURO Journal on Computational Optimization, 2016
In the aftermath of disasters such as major earthquakes, several roads may be blocked by rubble and the population tends to search refugee in certain gathering points of the city.

Control of interbank contagion under partial information [PDF]

open access: yes, 2014
International audienceWe consider a stylized core-periphery financial network in which links lead to the creation of projects in the outside economy but make banks prone to contagion risk.

Existence, coexistence and uniqueness of fixed points in parallel and sequential dynamical systems over directed graphs [PDF]

open access: yes, 2021
In this work, we solve the fixed-point existence, coexistence and uniqueness problems in the context of homogeneous parallel and sequential dynamical systems on maxterm and minterm Boolean functions over directed dependency graphs.

A Fluid Model of a Traffic Network with Information Feedback and Onramp Controls [PDF]

open access: yes, 2021
Funder: Charles Lee Powell Foundation; doi: http://dx.doi.org/10.13039/100008872AbstractUnlimited access to a motorway network can, in overloaded conditions, cause a loss of throughput. Ramp metering, by controlling access to the motorway at onramps, can

On bounding exact models of epidemic spread on networks [PDF]

open access: yes, 2017
In this paper we use comparison theorems from classical ODE theory in order to rigorously show that closures or approximations at individual or node level lead to mean-field models that bound the exact stochastic process from above.
