Characterizations of multinormality and corresponding tests of fit, including for Garch models
(Cornell University, 2018-05-22)
We provide novel characterizations of multivariate normality that incorporate both the characteristic function and the moment generating function, and we employ these results to construct a class of affine invariant, ...

Mixed integer linear programming and heuristic methods for feature selection in clustering
(Taylor & Francis, 2018)
This paper studies the problem of selecting relevant features in clustering problems, out of a data set in which many features are useless, or masking. The data set comprises a set U of units, a set V of features, a set R ...

Railway traffic disturbance management by means of control strategies applied to operations in the transit system
(WIT Press, 2018)
Railway systems in metropolitan areas support a high density of daily traffic that is exposed to different types of disturbances in the service. An interesting topic in the literature is to obtain action protocols in the ...

On Mathematical Optimization for the visualization of frequencies and adjacencies as rectangular maps
(ELSEVIER SCIENCE BV, 2018-02-18)
In this paper, we address the problem of visualizing a frequency distribution and an adjacency relation attached to a set of individuals. We represent this information using a rectangular map, i.e., a subdivision of a ...

Epigenetic features of human telomeres
(Oxford University Press, 2018)
Although subtelomeric regions in humans are heterochromatic, the epigenetic nature of human telomeres remains controversial. This controversy might have been influenced by the confounding effect of subtelomeric regions and ...

Mathematical programming formulations for the efficient solution of the k-sum approval voting problem
(Elsevier, 2018-10)
In this paper we address the problem of electing a committee among a set of m candidates and on the basis of the preferences of a set of n voters. We consider the approval voting method in which each voter can approve as ...

Minimum penalized φ-divergence estimation under model misspecification
(MDPI, 2018-04-30)
This paper focuses on the consequences of assuming a wrong model for multinomial data when using minimum penalized φ-divergence, also known as minimum penalized disparity estimators, to estimate the model parameters. These ...

A discretization result for some optimization problems in framework spaces with polyhedral obstacles and the Manhattan metric
(Elsevier, 2018-07)
In this work we consider the shortest path problem and the single facility Weber location problem in any real space of finite dimension where there exist different types of polyhedral obstacles or forbidden regions. These ...

On minimax and Pareto optimal security payoffs in multicriteria games
(Elsevier, 2018)
In this paper, we characterize minimax and Pareto-optimal security payoff vectors for general multicriteria zero-sum matrix games, using properties similar to the ones that have been used in the single criterion case. ...
