帮我用c语言写一个禁忌搜索算法

当然可以帮您编写禁忌搜索算法的C语言代码。禁忌搜索算法是一种启发式搜索算法，用于在大规模搜索空间中寻找最优解的近似解。以下是一个简单的禁忌搜索算法的示例代码：

#include <stdio.h>
#include <stdlib.h>

#define MAX_ITERATIONS 1000  // 最大迭代次数
#define TABU_SIZE 10         // 禁忌表大小

// 定义问题特定的解结构体
typedef struct {
    int x;
    int y;
} Solution;

// 定义问题相关的目标函数，这里假设需要最小化目标函数值
int objectiveFunction(Solution solution) {
    // TODO: 根据实际问题定义目标函数
    return (solution.x - 3) * (solution.x - 3) + (solution.y - 5) * (solution.y - 5);
}

// 定义禁忌搜索算法
void tabooSearch() {
    Solution currentSolution, bestSolution;
    int currentObjective, bestObjective;
    Solution tabuList[TABU_SIZE];

    // 初始化当前解和最优解
    currentSolution.x = rand() % 10;
    currentSolution.y = rand() % 10;
    currentObjective = objectiveFunction(currentSolution);
    bestSolution = currentSolution;
    bestObjective = currentObjective;

    // 初始化禁忌表
    for (int i = 0; i < TABU_SIZE; i++) {
        tabuList[i] = currentSolution;
    }

    // 开始迭代搜索
    int iteration = 0;
    while (iteration < MAX_ITERATIONS) {
        Solution nextSolution;
        int nextObjective = INT_MAX;

        // 在邻域中寻找下一个解
        for (int dx = -1; dx <= 1; dx++) {
            for (int dy = -1; dy <= 1; dy++) {
                if (dx == 0 && dy == 0) continue;  // 忽略当前解
                Solution neighbor;
                neighbor.x = currentSolution.x + dx;
                neighbor.y = currentSolution.y + dy;

                // 计算邻居解的目标函数值
                int neighborObjective = objectiveFunction(neighbor);

                // 检查是否是禁忌解
                int isTabu = 0;
                for (int i = 0; i < TABU_SIZE; i++) {
                    if (neighbor.x == tabuList[i].x && neighbor.y == tabuList[i].y) {
                        isTabu = 1;
                        break;
                    }
                }

                // 更新下一个解
                if (neighborObjective < nextObjective && !isTabu) {
                    nextSolution = neighbor;
                    nextObjective = neighborObjective;
                }
            }
        }

        // 更新当前解和禁忌表
        currentSolution = nextSolution;
        currentObjective = nextObjective;
        tabuList[iteration % TABU_SIZE] = currentSolution;

        // 更新最优解
        if (currentObjective < bestObjective) {
            bestSolution = currentSolution;
            bestObjective = currentObjective;
        }

        iteration++;
    }

    // 输出最优解
    printf("Best solution: x=%d, y=%d\n", bestSolution.x, bestSolution.y);
    printf("Best objective value: %d\n", bestObjective);
}

int main() {
    tabooSearch();
    return 0;
}

请注意，上述代码仅为禁忌搜索算法的一个简单示例，需要根据实际问题进行相应的修改和扩展。您可以根据自己的需求来定义问题特定的目标函数和解结构体，并进行适当的调整。希望这能帮到您！
