Basic Hyperactive Usage

from hyperactive.opt.gfo import HillClimbing
from surfaces.test_functions.algebraic import RastriginFunction

func = RastriginFunction(n_dim=5)

optimizer = HillClimbing(
    search_space=func.search_space,
    n_iter=100,
    experiment=func,
)
best_params = optimizer.solve()

print(f"Best params: {best_params}")
print(f"Best score: {func(best_params):.6f}")

Different Optimizers

from hyperactive.opt.gfo import (
    HillClimbing,
    RandomSearch,
    SimulatedAnnealing,
)
from surfaces.test_functions.algebraic import RastriginFunction

func = RastriginFunction(n_dim=5)

optimizers = [
    ('HillClimbing', HillClimbing),
    ('RandomSearch', RandomSearch),
    ('SimAnnealing', SimulatedAnnealing),
]

for name, OptClass in optimizers:
    optimizer = OptClass(
        search_space=func.search_space,
        n_iter=100,
        experiment=func,
    )
    best = optimizer.solve()
    print(f"{name}: {func(best):.6f}")
