Using GAs To Deal With Dynamic Environments: A Comparative Study Of Several Approaches Based On Promoting Diversity
Anabela Simões, Ernesto J. F. Costa · 2002
Most approaches used in EAs for problems in which the environment changes from time to time, try to preserve the diversity of the population. One of those approaches applies a new biologically inspired genetic operator called transformation (Simoes & Costa, 2001). We tested two EAs using transformation (TGA and ETGA) and two other classical approaches: random immigrants (RIGA) and hypermutation (HMGA). The comparative study was made using the dynamic 0/1 Knapsack optimization problem.
