Eigendecomposition of the Mean-Variance Portfolio Optimization Model,sult of this decomposition can be given an interpretation in terms of uncorrelated eigenportfolios. When only some of the eigenvalues and eigenvectors are used, the resulting mean-variance problem is an approximation of the original one. A solution to the approximation yields lower and upper bounds

Three Aspects of the Research Impact by a Scientist: Measurement Methods and an Empirical Evaluatioover (a) citation metrics and (b) merit metrics. The third one relates to the level of results. It involves a taxonomy of the research field, that is, a hierarchy representing its composition. The impact is evaluated according to the taxonomy ranks of the subjects that have emerged or have been cruc

SVM Classification of Uncertain Data Using Robust Multi-Kernel Methods, not addressed efficiently. Furthermore, while traditional SVM methods use a single kernel for learning, multiple kernel schemes are being developed to incorporate a better understanding of all the data features. We combine the multiple kernel learning methods with the robust optimization concepts t

A Time-Indexed Generalized Vehicle Routing Model and Stabilized Column Generation for Military Aircraft should attack a number of ground targets so that the total expected effect is maximized. The model is a rich vehicle routing problem and the direct application of a general solver is practical only for scenarios of very moderate sizes. We propose a Dantzig–Wolfe reformulation and column generat
