Applying ranking and selection procedures to long-term mitigation for improved network restoration

open access: yesEURO Journal on Computational Optimization, 2016
In this paper, we consider methods to determine the best single arc mitigation plan for improving rapid recovery of a network with a given level of statistical certainty.

Solving the maximum edge-weight clique problem in sparse graphs with compact formulations

open access: yesEURO Journal on Computational Optimization, 2015
This paper studies the behavior of compact formulations for solving the maximum edge-weight clique (MEWC) problem in sparse graphs. The MEWC problem has long been discussed in the literature, but mostly addressing complete graphs, with or without a ...

Nash equilibria set computing in finite extended games [PDF]

open access: yesComputer Science Journal of Moldova, 2006
he Nash equilibria set (NES) is described as an intersection of graphs of best response mappings. The problem of NES computing for multi-matrix extended games is considered. A method for NES computing is studied.

Optimal capacitated ring trees

open access: yesEURO Journal on Computational Optimization, 2016
We study a new network design model combining ring and tree structures under capacity constraints. The solution topology of this capacitated ring tree problem (CRTP) is based on ring trees which are the union of trees and 1-trees.

Fast algorithms for large scale generalized distance weighted discrimination [PDF]

open access: yes, 2017
High dimension low sample size statistical analysis is important in a wide range of applications. In such situations, the highly appealing discrimination method, support vector machine, can be improved to alleviate data piling at the margin.

A modification of the αBB method for box-constrained optimization and an application to inverse kinematics

open access: yesEURO Journal on Computational Optimization, 2016
For many practical applications it is important to determine not only a numerical approximation of one but a representation of the whole set of globally optimal solutions of a non-convex optimization problem.

Convex Programs for Temporal Verification of Nonlinear Dynamical Systems [PDF]

open access: yes, 2007
A methodology for safety verification of continuous and hybrid systems using barrier certificates has been proposed recently. Conditions that must be satisfied by a barrier certificate can be formulated as a convex program, and the feasibility of the ...

A tight MIP formulation of the unit commitment problem with start-up and shut-down constraints

open access: yesEURO Journal on Computational Optimization, 2017
This paper provides the convex hull description of the single thermal Unit Commitment (UC) problem with the following basic operating constraints: (1) generation limits, (2) start-up and shut-down capabilities, and (3) minimum up and down times.

A Combinatorial Optimization Approach to the Selection of Statistical Units [PDF]

open access: yes, 2015
In the case of some large statistical surveys, the set of units that will constitute the scope of the survey must be selected. We focus on the real case of a Census of Agriculture, where the units are farms.
