## Examples with Mealpy <= 2.5.4

from mealpy.bio_based import SMA

ackey = Ackley02()

## Run the algorithm
model = SMA.OriginalSMA(epoch=100, pop_size=50, pr=0.03)

print(f"Best solution: {best_position}, Best fitness: {best_fitness}")

print(ackey.n_fe)
print(ackey.f_global)
print(ackey.x_global)


## Examples with Mealpy >= 3.0.0

from opfunu.cec_based import cec2017
f3 = cec2017.F32017(ndim=30)

from mealpy import GA, FloatVar

    "minmax": "min",
}
model = GA.BaseGA(epoch=100, pop_size=50)
gbest = model.solve(problem_dict1)
print(f"Solution: {gbest.solution}, Fit: {gbest.target.fitness}")
