• #### Artificial bee colony and particle swarm optimization for the estimation of nonlinear regression parameters ﻿

(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 ...

(2009-02-20)
In this paper an heuristic algorithm is developed. Its implementation is developedas well, in order to solve a sampling problem in the urban transportation network in Mexico City. The problem consist of the selection of ...
• #### Estimación de parámetros de regresión no lineal mediante colonia de abejas artificiales ﻿

(2013-04-04)
Este trabajo presenta los resultados de la técnica heurística de ABC (Artificial Bee Colony) utilizada para estimar los parámetros de modelos de regresión no lineal. El algoritmo fue probado sobre 27 bases de datos de la ...
• #### Fuzzy Regression VS. Ordinary Least Squares Regression: Case Study ﻿

(2011-03-18)
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 ﻿

(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 ...
• #### Heuristics for the Robust Coloring Problem ﻿

(2011-03-18)
Let $G$ and $\bar{G}$ be complementary graphs. Given a penalty function defined on the edges of $G$, we will say that the rigidity of a $k$-coloring of $G$ is the sum of the penalties of the edges of G joining vertices of ...
• #### Método heurístico para particionamiento óptimo ﻿

(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 ﻿

(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 ...
• #### Simulated Annealing–Golden section algorithm for the multiproduct replenishment problem with stochastic demand. ﻿

(2010-07-02)
The joint replenishment problem (JRP) has been studied for over 30 years and there are both heuristic and exact algorithms to determine the frequency of orders and fundamental cycle; in recent years ithas been considered ...
• #### Un Algoritmo Evolutivo para Resolver el Problema de Coloración Robusta ﻿

(2012-03-22)
Let G and \bar{G} be two complementary graphs. Given a penalty function defined over the edges of \bar{G}, it is said that the rigidity of a k-coloring of G is the summation ofthe penalties of the edges of G that join ...
