The official implementation of GMOEA [1] with Pytorch:
GMOEA.py is the main file.
GAN_model.py is the GAN model used in GMOEA.
IMMOEA_pro.py: IMF test problems
global_parameter.py is the class including the general parameters for running GMOEA.
mating_selection.py is the mating selection strategy used in GMOEA. Specifically, the mating selection strategy in RSEA [2] is used.
spea2_env.py is the environmental selection strategy used in GMOEA. Specifically, the environmental selection strategy in SPEA2 [3] is used.
NDSort.py is the non-dominated sorting method using the efficient non-dominated sorting method in [4].
EAreal.py is the simulated binary crossover and polynomial mutation.
PM_mutation.py is the polynomial mutation [5].
tournament.py is the K-tournament selection [6].
