## Abstract

This paper introduces the rst genetic algorithm approach for solving the Band Collocation Problem (BCP) which is a combinatorial optimization problem that aims to reduce the hardware costs on ber optic networks. This problem consists of nding an optimal permutation of rows of a given binary rectangular matrix representing a communication network so that the total cost of covering all 1's by Bands is minimum. We present computational results which indicate that we can obtain almost optimal solutions of moderately large size instances (up to 96 rows and 28 columns) of the BCP within a few seconds.
