We study the function returning the sum of the k components of largest magnitude of a vector. We show that if a nonnegative vector x is such that its Eu...

The fundamental limits of remote estimation of Markov processes under communication constraints are presented. The remote estimation system consists of a sen...

The first part of this two-part paper developed the framework for characterizing the feasibility regions of power systems in the demand space. This character...

This two-part paper presents a framework for the characterization and minimal representation of the feasibility regions of power systems in the demand space....

This paper presents a structured approach to model logical constraints (expressions that contain propositions and logical operators) in a linear program usin...

A new algorithm for the optimal stope design problem is proposed. It is based on a previous methodology developed by Bai et al. (2013a) where a cylindrical ...

This paper provides an overview of the role, past, present and future, of demand-side management and demand-side response in electric grids. We address the f...

We propose a primal algorithm for the Set Partitioning Problem based on the Integral Simplex Using Decomposition of Zaghrouti et al. (2014). We present the a...

The maximally diverse grouping problem requires finding a partition of a given set of elements into a fixed number of mutually disjoint subsets (or groups) i...

In this paper we propose a general variable neighborhood search heuristic for solving the uncapacitated single allocation p-hub center problem (USApHCP). F...

The uncapacitated multiple allocation p-hub center problem (UMApHCP) consists of choosing p hub locations from a set of nodes with pairwise traffic deman...

Usually several neighborhood structures may be explored within a single local search algorithm. The simplest way is to define a single neighborhood as a unio...

In this paper we investigate the options of a network operator faced with the requirement of reducing its carbon footprint, expressed in terms of a global en...

In this paper we show that the Clique Partitioning Problem can be reformulated in an equivalent form as the Maximally Diverse Grouping Problem (MDGP). We th...

In the present paper, we are interested in bounding differences between graph invariants as well as in characterizing the corresponding extremal graphs. This...

This paper proposes an incentive mechansim for transmission expansion planning. The mechansim is a bilevel program. The upper level is a profit-maximizing tr...

This paper proposes models and algorithms for the pickup and delivery vehicle routing problem with time windows and multiple stacks. Each stack is rear-loade...

In this paper we show how to robustify the computation of equilibria in two integrated assessment models for climate change. Both models deal with the optima...

Studies of traffic dynamics rely either on macroscopic models considering the traffic as a fluid, or on microscopic models of drivers' behavior. The connec...

In this paper, we present a stochastic two-level optimization model whose upper-level problem depicts a wastewater treatment plant deciding on the size of co...
