Mohamad Hossein Fazel Zarandi; Solmaz Ghazanfar Ahari; Nader Ghaffari-Nasab

Volume 10, Issue 27 , January 2012, Pages 22-43

  Estimating the optimal number of clusters in an unsupervisedpartitioning of data sets has been a challenging area in recent years.These indices usually use two criteria called compactness andseparation to evaluate the efficiency of the performed clustering. Inthis paper a new separation measure for ECAS ...  Read More

An Artificial Bee Colony algorithm approach for locating optimal switch location in cellular mobile communication network

S.M. Ali Khatami Firouzabadi; Amin Vafadar Nikjoo

Volume 10, Issue 27 , January 2012, Pages 44-67

  In this research, we use Artificial Bee Colony (ABC) algorithm tosolve cell to switch assignment problem (CTSAP) that is NP-hard. InCTSAP, there are cells and switches in which cells locations arepredetermined. The objective of problem is optimal assigning of cellsto switches with minimum cost. Here, ...  Read More
