テスト関数に対する最適化例¶

ここでは、Rastrigin 関数というテスト関数をブラックボックスと見なして、これに対してブラックボックス最適化を実施します。

Rastrigin 関数は、以下の式で記述できる著名な多峰性の関数です。

\[ f(\mathbf{x}) = 10 n + \sum_{i=1}^{n} \left( x_i^2 - 10 \cos(2\pi x_i) \right) \]

ここで、\(n\) は次元数で、\(\boldsymbol{x}\) は入力ベクトルです。この関数は、多数の局所最適解を持ち、グローバルな最小値は、\(\boldsymbol{x}=0\) のとき \(f(\boldsymbol{x})=0\) をとります。\(n=2\) の場合、Rastrigin 関数は以下のような分布を有します。

ブラックボックス関数の準備¶

まず、実数決定変数とブラックボックス関数を作成します。本サンプルプログラムでは、5 次元 (\(n=5\)) の Rastrigin 関数を対象とします。

from datetime import timedelta

import numpy as np
from amplify_bbopt import DiscretizationSpec, RealVariable, blackbox


# Rastrigin 関数の定義
def rastrigin_function(x: list[float]) -> float:
    """A test function, yieldng the global min of 0 at (0, 0, ...).

    Args:
        x (list[float]): An input vector.

    Returns:
        float: The function value.
    """
    return (
        10 * len(x)
        + (np.array(x) ** 2 - 10 * np.cos(2 * np.pi * np.array(x))).sum()
    )


# 問題・条件設定
rng = np.random.default_rng()
num_vars = 5  # 問題次元 (実数決定変数数)
var_min = -3.0  # 実数決定変数の最小値
var_max = 3.0  # 実数決定変数の最大値
disc_spec = DiscretizationSpec(num_bins=101)  # 離散点数を 101 に設定

# 実数決定変数リストの作成
x_list = [
    RealVariable((var_min, var_max), discretization_spec=disc_spec)
    for _ in range(num_vars)
]


# ブラックボックス関数の定義
@blackbox
def func(input_x: list[float] = x_list) -> float:  # type: ignore
    return rastrigin_function(input_x)

最適化の実行¶

最適化で利用するイジングマシン (Fixstars Amplify Annealing Engine (Amplify AE))をソルバークライアントとして設定します。ここでは、一度のアニーリング時間を 2 秒と設定します。

準備したブラックボックス関数とソルバークライアントを使い、最適化クラスのインスタンス化を行います。また、初期学習データを 10 サンプルランダム生成し、データセットに追加します。

Optimizer.optimize を使って最適化サイクルを実行します。

from amplify import FixstarsClient
from amplify_bbopt import KMTrainer, Optimizer

# イジングマシンの設定
client = FixstarsClient()
client.parameters.timeout = timedelta(seconds=2)
# client.token = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"  # ローカル環境等で使用する場合は、Amplify AEのアクセストークンを入力してください。

# 最適化クラスのインスタンス化
optimizer = Optimizer(blackbox=func, trainer=KMTrainer(), client=client)

# 初期学習データの作成 (最適化クラスのメソッド利用)
num_init_data = 10
optimizer.add_random_training_data(num_data=num_init_data)

# 最適化を実行
optimizer.optimize(num_iterations=100)

# 最適化結果の表示
print(f"{optimizer.best.values=}")
print(f"{optimizer.best.objective=}")

結果の可視化¶

最適化クラスインスタンスが持つ履歴情報に基づき、最適化履歴を可視化します。また、ベスト解の出力も可能です。

import matplotlib.pyplot as plt


def plot_optimization_history(optim: Optimizer, num_init: int) -> None:
    # 初期学習データの履歴
    objective_init = optim.training_data.y[:num_init]

    # アニーリングから直接得られた最良解の履歴
    objective_anneal = [
        float(h.annealing_best_solution.objective) for h in optim.history
    ]

    plt.plot(range(-num_init + 1, 1), objective_init, "blue")
    plt.plot(range(1, len(objective_anneal) + 1), objective_anneal, "-r")
    plt.xlabel("Cycles")
    plt.ylabel("Objective value")
    plt.grid(True)
    plt.show()

学習データを指数変換した場合¶

Optimizer.optimize の引数 surrogate_data_transformer に ExpScaler を設定することで学習データの目的関数値に対して指数変換を施すことができます。詳細はこちらを参照してください。
