双色球彩票 利用java模拟冷却算法 选号，给出java代码

好的，这里给出一个基于冷却算法的双色球选号Java代码示例，供参考：

import java.util.Arrays;
import java.util.Random;

public class DoubleColorBall {
    // 双色球的号码范围和选号规则
    private static final int[] RED_BALL_RANGE = {1, 33};
    private static final int[] BLUE_BALL_RANGE = {1, 16};
    private static final int RED_BALL_COUNT = 6;
    private static final int BLUE_BALL_COUNT = 1;

    // 初始温度和降温速率
    private static final double INITIAL_TEMPERATURE = 100.0;
    private static final double COOLING_RATE = 0.03;

    // 冷却算法参数
    private static final int MAX_ITERATIONS = 1000;
    private static final int MAX_REJECTIONS = 50;
    private static final double MINIMUM_TEMPERATURE = 1e-8;

    // 随机数生成器
    private static final Random random = new Random();

    // 计算当前号码组合的得分
    private static int calculateScore(int[] candidate, int[] winning) {
        int score = 0;
        for (int i = 0; i < RED_BALL_COUNT; i++) {
            if (Arrays.binarySearch(winning, candidate[i]) >= 0) {
                score++;
            }
        }
        if (candidate[RED_BALL_COUNT] == winning[RED_BALL_COUNT]) {
            score += 2;
        }
        return score;
    }

    // 冷却函数
    private static double coolingFunction(double temperature) {
        return temperature * (1 - COOLING_RATE);
    }

    // 生成新的号码组合
    private static int[] generateNewCandidate(int[] current) {
        int[] candidate = Arrays.copyOf(current, current.length);
        int index = random.nextInt(RED_BALL_COUNT);
        candidate[index] = random.nextInt(RED_BALL_RANGE[1] - RED_BALL_RANGE[0] + 1) + RED_BALL_RANGE[0];
        if (random.nextDouble() < 0.5) {
            candidate[RED_BALL_COUNT] = random.nextInt(BLUE_BALL_RANGE[1] - BLUE_BALL_RANGE[0] + 1) + BLUE_BALL_RANGE[0];
        }
        return candidate;
    }

    // 计算接受新的号码组合的概率
    private static double acceptanceProbability(int currentScore, int newScore, double temperature) {
        if (newScore > currentScore) {
            return 1.0;
        }
        double delta = currentScore - newScore;
        return Math.exp(delta / temperature);
    }

    // 冷却算法
    private static int[] simulateAnnealing(int[] winning) {
        // 初始化当前号码组合
        int[] current = new int[RED_BALL_COUNT + BLUE_BALL_COUNT];
        for (int i = 0; i < RED_BALL_COUNT; i++) {
            current[i] = random.nextInt(RED_BALL_RANGE[1] - RED_BALL_RANGE[0] + 1) + RED_BALL_RANGE[0];
            for (int j = 0; j < i; j++) {
                if (current[i] == current[j]) {
                    i--;
                    break;
                }
            }
        }
        current[RED_BALL_COUNT] = random.nextInt(BLUE_BALL_RANGE[1] - BLUE_BALL_RANGE[0] + 1) + BLUE_BALL_RANGE[0];

        // 初始化最优解和得分
        int[] best = Arrays.copyOf(current, current.length);
        int bestScore = calculateScore(current, winning);

        // 初始化温度和迭代次数
        double temperature = INITIAL_TEMPERATURE;
        int iterations = 0;

        // 开始冷却过程
        while (temperature > MINIMUM_TEMPERATURE && iterations < MAX_ITERATIONS) {
            int rejections = 0;
            while (rejections < MAX_REJECTIONS) {
                int[] candidate = generateNewCandidate(current);
                int candidateScore = calculateScore(candidate, winning);
                double probability = acceptanceProbability(bestScore, candidateScore, temperature);
                if (probability > random.nextDouble()) {
                    current = Arrays.copyOf(candidate, candidate.length);
                    if (candidateScore > bestScore) {
                        best = Arrays.copyOf(candidate, candidate.length);
                        bestScore = candidateScore;
                    }
                } else {
                    rejections++;
                }
            }
            temperature = coolingFunction(temperature);
            iterations++;
        }
        return best;
    }

    // 测试
    public static void main(String[] args) {
        int[] winning = {1, 2, 3, 4, 5, 6, 7}; // 中奖号码
        int[] selected = simulateAnnealing(winning); // 选号
        System.out.println("中奖号码：" + Arrays.toString(winning));
        System.out.println("选号结果：" + Arrays.toString(selected));
        System.out.println("得分：" + calculateScore(selected, winning));
    }
}

这段代码实现了基于冷却算法的双色球选号功能。其中，simulateAnnealing方法实现了冷却算法的过程，calculateScore方法用于计算号码组合的得分，coolingFunction方法用于计算温度的降温过程，generateNewCandidate方法用于生成新的号码组合，acceptanceProbability方法用于计算接受新号码组合的概率。在main方法中，我们可以定义中奖号码和调用simulateAnnealing方法来进行选号，最后输出选号结果和得分。
