The aim of this paper is to compute upper and lower bounds for convex value functions of derivative contracts. Laprise et al. (2006) compute bounds for Ame...

This paper presents a decomposition approach for solving a variant of the Routing and Wavelength Assignment (RWA) problem, in which all connection requests a...

We model the role of the world's forests as a major carbon sink and consider the impact that forest depletion has on the accumulation of CO<sub>2</sub> in ...
BibTeX referenceFranchise Location Models and Cannibalization Effects: A Variable Neighborhood Search Approach
Application of the dispersion models in order to address the cannibalization phenomenon within franchised chains is a new approach. In this work we have deve...
BibTeX reference
Community detection in networks has been studied extensively in the last decade. Many criteria, expressing the quality of the partitions obtained, as well ...
BibTeX reference
A travelling deliveryman needs to find a tour such that the total waiting time of all the customers he has to visit is minimum. The deliveryman starts his ...

Euclidean Minimum Sum-of-Squares Clustering amounts to finding <i>p</i> prototypes by minimizing the sum of the squared Euclidean distances from a set of ...
BibTeX reference
Although General Variable Neighborhood Search (GVNS) is shown to be powerful and robust methodology for solving travelling salesman and vehicle routing pro...
BibTeX reference
Sequential clustering aims at determining homogeneous and/or well-separated clusters within a given set of entities, one at a time, until no more such clus...
BibTeX reference
Reduced RLT constraints are a special class of Reformulation-Linearization Technique (RLT) constraints. They apply to nonconvex (both continuous and mixed-...
BibTeX reference
Given a set of entities, cluster analysis aims at finding subsets, also called clusters or communities or modules, entities of which are homogeneous and well...
BibTeX reference
The past decade has seen advances in general methods for symmetry breaking in mixed-integer linear programming. These methods are advantageous for general ...
BibTeX reference
The production routing problem (PRP) concerns the production and distribution of a single product from a production plant to multiple customers using capacit...
BibTeX reference
We consider a two-period closed-loop supply chain (CLSC) game where a remanufacturer appropriates of the returns' residual value and decides whether to exc...
BibTeX reference
In this paper, we provide a decomposition over time of Shapley value for dynamic stochastic discrete-time games, where the uncertainty is described by an eve...
BibTeX reference
Blackbox optimization typically arises when the functions defining the objective and constraints of an optimization problem are computed through a computer...
BibTeX reference
Finding clusters, or communities, in a graph, or network is a very important problem which arises in many domains. Several models were proposed for its solu...
BibTeX reference
Convex nondifferentiable, also known as convex nonsmooth, optimization (NDO) looks at problems where the functions involved are not continuously different...
BibTeX reference
This paper is concerned with computing global optimal solutions for maximum k-cut problems. We improve on the SBC algorithm of Ghaddar, Anjos and Liers in...
