In this article we investigate some strategies for solving set partitioning problems (SPP), in particular the gains in computational efficiency that can be...

Decentralized sequential hypothesis testing refers to a generalization of Wald's sequential hypothesis testing setup in which multiple decision makers make ...

Various disturbances such as adverse weather conditions may result in delayed or canceled flights and affect the optimized schedules planned for airline crew...

This paper considers a family of cutting planes, recently developed for mixed 0-1 polynomial programs and shows that they define facets for the maximum edge-...

In prior works, this group demonstrated the feasibility of valid adaptive sequential designs for crossover bioequivalence studies. In this paper, we extend t...

Tropical algebra is the algebra constructed over the tropical semifield \(\mathbb{R}_{max}\). After revisiting the classification of 2-dimensional `(\math...

The empirical Receiver Operating Characteritic (ROC) curve can be used to evaluate the properties of a diagnostic test from the distribution of a variable on...

Pressure on ancillary reserves in power systems has significantly mounted due to the recent generalized increase of the fraction of (highly fluctuating) wi...

Currently, power system operations planning practices are undergoing various transformations in an attempt to integrate efficiently significant amounts of su...

The types of constraints encountered in black-box and simulation-based optimization problems differ significantly from those treated in nonlinear programmin...

In biomedical research there is a growing interest in the use of hierarchical Poisson regression models. Although sample size calculations for testing pa...

We introduce an efficient approach to evaluate counterparty risk and we compute the Credit Valuation Adjustement for derivatives having early exercise feat...

Given a complete directed graph \(G\) with weights on the vertices and on the arcs, a \(\theta\)-improper \(k\)-coloring is an assignment of at most `...

Nowadays, tremendous data are continuously gathering from the smart card in public transport domain. Such data, conveying two viable distinct information, ca...

The widespread proliferation of Internet and wireless applications has produced a significant increase of ICT energy footprint. As a response, in the last fi...

It is well known that the mixed linear complementarity problem can be used to model the equilibrium in energy markets as well as a host of other engineering ...

We consider the class of stochastic games played over finite event trees, that is, games where the random process is an act of nature and is not influenced b...
