Bounded Variables nonlinear Multiple Criteria Optimization using Scatter search
Bounded Variables nonlinear Multiple Criteria Optimization using Scatter search
(2011-05-06)
This paper introduces an adaptation of multiple criteria scatter search to deal with nonlinear continuous vector optimization problems on bounded variables, applying Tabu Search approach as diversification generator method. ...

Análisis estadístico de datos categóricos ordenados
(2009-02-18)
Ordered categorical panel data is modeled assuming an underlying continuous-time finite-space Markov chain. The tridiagonal form of the intensity matrix renders the implementation of the maximum likelihood method more ...
Curvas ROC y Vecinos Cercanos, Propuesta de un Nuevo Algoritmo de Condensación
Curvas ROC y Vecinos Cercanos, Propuesta de un Nuevo Algoritmo de Condensación
(2011-03-18)
k-NN criteria are non parametric methods of statistical classificaction. They are accurate, versatile and distribution free. However, their computational cost may be too expensive; especially for large sample sizes. We ...
Application of a cognitive model of emotional appraisal to the board evaluation function of a program that plays chess
Aplicación de un modelo cognitivo de valoración emotiva a la función de evaluación de tableros de un programa que juega ajedrez
(2012-07-01)
This paper describes the analysis and design of a cognitive emotional assesment model. This model is based on the goals looked for a chess player during a game. The model affects the output of the board evaluation function ...
On a variational principle for shape optimization and elliptic free boundary problems
On a variational principle for shape optimization and elliptic free boundary problems
(2009-02-18)
A variational principle for several free boundary value problems using a relaxation approach is presented. The relaxed Energy functional is concave and it is defined on a convex set, so that the minimizing points are ...
El "unravelling" para bigráficas diferenciales
El 'unravelling' para bigráficas diferenciales
(2009-02-18)
Here are examined the main properties of the algorithm called ¨unravelling¨ for differential bigraphs. This algorithm was originally developed for differential graded categories and was useful in the proof the celebrated ...
De la fórmula de sumación de Poisson a los teoremas de muestreo y reconstrucción
(2012-03-22)
Los radioastrónomos miden la visibilidad de una fuente luminosa para determinar la cantidad de luz emitida y su distribución, bajo el principio que esta es la transformada de Fourier de la visibilidad. En la teoría de la ...
search of hadamard matrices by turyn sequences
Búsqueda de Matrices de Hadamard a través de Secuencias de Turyn
(2011-07-08)
In this paper we study the Hadamard matrices and some algorithms to generate them. We review some theoretical aspects about Hadamard's conjecture, which asserts that every positive integer multiple of 4 is a Hadamard number. ...
Optimiza - un paquete computacional para la optimización de problemas no lineales
Optimiza - un paquete computacional para la optimización de problemas no lineales
(2009-02-18)
Our goal is to build a software able to solve problems in non linear optimization. A central point is selection of the algorithm, which is based on Augmented Lagrangian Method combined with quasi-Newton methods (BFGS, ...
Spatial interpolation of dry deposition using EOF models
Spatial interpolation of dry deposition using EOF models
(2009-02-19)
Random processes are monitored over space and time by a network of stations distributed across a spatial region. Auxiliary information is often gathered not only at the stations but at other points across the region. The ...
