A symbiotic evolutionary algorithm for dynamic facility layout problem

Abstract

A symbiotic evolutionary algorithm (SymEA) for dynamic facility layout problem (DFLP) is developed and tested. SymEA differs from the existing EA approaches for DFLP in two ways: first, it adopted a coevolutionary multi-population approach, second, the generational replacement strategy (/spl mu/, /spl lambda/)-selection of evolution strategies is used to refine the symbiotic relationship.
