    • Aplicación de la búsqueda tabú en regresión no lineal 

      Villalobos Arias, Mario; Trejos Zelaya, Javier; de los Cobos Silva, Sergio Gerardo (2009-02-20)
      We implement the combinatorial optimization technique known as tabu search inthe parameter estimation problem in a given non linear model. For the generationof neighbors, the implementation is based on a discretization of ...
    • Artificial bee colony and particle swarm optimization for the estimation of nonlinear regression parameters 

      de los Cobos Silva, Sergio Gerardo; Gutiérrez Andrade, Miguel Ángel; Rincón García, Eric Alfredo; Lara Velázquez, Pedro; Aguilar Cornejo, Manuel (2014-04-03)
      This paper shows the comparison results of ABC (Artificial Bee Colony) and PSO (Particle Swarm Optimization) heuristic tech- niques that were used to estimate parameters for nonlinear regression models. The algorithms were ...
    • Asignación de frecuencias en telefonía celular aplicando el problema de coloracion robusta

      The objective of this paper is to disseminate the technique of fuzzy regression and to give a practical example of its use. To this end, classical regression is compared to several fuzzy regression models on a problem ...
    • General guidelines solution for linear programming with fuzzy coefficients 

      de los Cobos Silva, Sergio Gerardo; Terceño Gómez, Antonio; Gutiérrez Andrade, Miguel Ángel (2013-08-29)
      This work introduce to the Possibilistic Programming and the Fuzzy Programming as paradigms that allow to resolve problems of linear programming when the coefficients of the model or the restrictions on the same are presented ...
    • Método heurístico para particionamiento óptimo 

      de los Cobos Silva, Sergio Gerardo; Trejos Zelaya, Javier; Pérez Salvador, Blanca Rosa; Gutiérrez Andrade, Miguel Ángel (2009-02-20)
      Many data analysis problems deal with non supervised partitioning of a data set,in non empty clusters well separated between them and homogeneous within the clusters.An ideal partitioning is obtained when any object can ...
    • New geometrical compactness measures for zones design 

      Rincón García, Eric Alfredo; Gutiérrez Andrade, Miguel Ángel; de los Cobos Silva, Sergio Gerardo; Lara Velázquez, Pedro (2012-07-01)
      The design of compact zones has been studied because of its influence in the creation of zones with regular forms, which are easier to analyze, to investigate or to administer. This paper propose a new method to measure ...
