    • Heuristics for the Robust Coloring Problem 

      Gutiérrez Andrade, Miguel Ángel; Lara Velázquez, Pedro; Lopez Bracho, Rafael; Ramírez Rodríguez, Javier (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

      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 ...
