Bump optuna from 3.2.0 to 3.3.0

[dependabot]

Bumps optuna from 3.2.0 to 3.3.0.

Release notes

Sourced from optuna's releases.

v3.3.0

This is the release note of v3.3.0.

Highlights

CMA-ES with Learning Rate Adaptation

A new variant of CMA-ES has been added. By setting the lr_adapt argument to True in CmaEsSampler, you can utilize it. For multimodal and/or noisy problems, adapting the learning rate can help avoid getting trapped in local optima. For more details, please refer to #4817. We want to thank @​nomuramasahir0, one of the authors of LRA-CMA-ES, for his great work and the development of cmaes library.

Hypervolume History Plot for Multiobjective Optimization

In multiobjective optimization, the history of hypervolume is commonly used as an indicator of performance. Optuna now supports this feature in the visualization module. Thanks to @​y0z for your great work!

Constrained Optimization Support for Visualization Functions

Plotly	matplotlib

Some samplers support constrained optimization, however, many other features cannot handle it. We are continuously enhancing support for constraints. In this release, plot_optimization_history starts to consider constraint violations. Thanks to @​hrntsm for your great work!

import optuna
def objective(trial):
x = trial.suggest_float("x", -15, 30)
y = trial.suggest_float("y", -15, 30)
v0 = 4 * x2 + 4 * y2
trial.set_user_attr("constraint", [1000 - v0])
return v0
def constraints_func(trial):
return trial.user_attrs["constraint"]
sampler = optuna.samplers.TPESampler(constraints_func=constraints_func)
study = optuna.create_study(sampler=sampler)
study.optimize(objective, n_trials=100)
fig = optuna.visualization.plot_optimization_history(study)
fig.show()
