这是一个简单的禁忌搜索算法,用于求解卡车无人机路径问题。以下是Matlab代码:
```matlab
% 初始化
clear all;
clc;
n = 10; % 随机生成的城市数量
maxIter = 1000; % 最大迭代次数
tabuLength = 10; % 禁忌表长度
tabuList = zeros(n, n); % 禁忌表
currentSolution = randperm(n); % 当前解
bestSolution = currentSolution; % 最优解
bestCost = tspfun(bestSolution); % 最优解的成本
currentCost = bestCost; % 当前解的成本
iter = 1; % 迭代次数
% 算法主循环
while iter < maxIter
% 构造候选解集
candidateList = cell(n, 1);
for i = 1:n
for j = i+1:n
candidateList{i} = [candidateList{i}, j];
end
end
% 找出最好的候选解
bestCandidateCost = Inf;
for i = 1:n
for j = 1:length(candidateList{i})
if tabuList(i, candidateList{i}(j)) == 0
newSolution = currentSolution;
newSolution([i, candidateList{i}(j)]) = newSolution([candidateList{i}(j), i]);
newCost = tspfun(newSolution);
if newCost < bestCandidateCost
bestCandidate = [i, candidateList{i}(j)];
bestCandidateCost = newCost;
end
end
end
end
% 更新当前解和最优解
currentSolution(bestCandidate) = currentSolution([bestCandidate(2), bestCandidate(1)]);
currentCost = bestCandidateCost;
if currentCost < bestCost
bestSolution = currentSolution;
bestCost = currentCost;
end
% 更新禁忌表
tabuList = max(tabuList - 1, 0);
tabuList(bestCandidate(1), bestCandidate(2)) = tabuLength;
% 输出迭代信息
fprintf('Iter: %d, Cost: %f\n', iter, bestCost);
% 更新迭代次数
iter = iter + 1;
end
% 可视化结果
figure;
plot([bestSolution, bestSolution(1)], 'o-');
title(sprintf('Best Solution: %f', bestCost));
xlabel('City Index');
ylabel('Order');
```
其中,tspfun函数是计算旅行商问题的成本函数,可以根据实际情况进行修改。
