Generalized convexity: Their applications to variational problems [Article]
(Sociedad de Estadística e Investigación Operativa, 2015-07)
The aim of this paper is to show one of the generalized convexity applications, generalized monotonicity particularly, to the variational problems study. These problems are related to the search of equilibrium conditions ...
Un esquema general de búsqueda local en programación entera. Evaluación computacional [Presentation]
En este trabajo, estudiamos un procedimiento general de búsqueda local basado en un sistema probabilístico de entornos, que puede ser combinada con técnicas de “annealing” simulado y de banda inferior. Para ello, se estudia ...
Generalizations of nondifferentiable convex functions and some characterizations [Presentation]
In this paper we generalize the convex functions, defining the concept of preconvex function and we study some characterizations by intervals, some characterizations by polytopes, some characterizations by level sets, ...
Local influence on the general linear model [Article]
(Indian Statistical Institute, 1998)
We study the Local Influence on the General Linear Model with a perturbation scheme in the variance-covariance matrix of the random errors. The comparison of the results obtained and the conditional bias have been used to ...

Minimum spanning trees with neighborhoods: mathematical programming formulations and solution methods [Article]
This paper studies Minimum Spanning Trees under incomplete information for its vertices. We assume that no information is available on the precise placement of vertices so that it is only known that vertices belong to some ...
Some remarks on optimality conditions for fuzzy optimization problems [Article]
(Universidad de La Habana, 2017)
In this article we present a new concept of stationary point for gH-differentiable fuzzy functions which generalize previous concepts that exist in the literature. Also, we give a concept of generalized convexity for ...

Population pharmacokinetics of colistin: implications for clinical use for Gram-negative pathogens [Presentation]
The objective of this study was to characterize the pharmacokinetics of colistin methanesulphonate (CMS) and colistin in critically ill patients following the administration of a 4.5 MU CMS loading dose follow by 3MU CMS ...
