% 定义无人机起始位置和目标位置
start_point = [0, 0, 0]; % 起始位置 [x, y, z]
target_point = [100, 100, 100]; % 目标位置 [x, y, z]

% 定义城市地形和障碍物信息
city_map = imread(‘city_map.png’); % 城市地形图像
obstacles = [
20, 30, 10; % 障碍物1位置 [x, y, z]
50, 60, 20; % 障碍物2位置 [x, y, z]
80, 90, 15; % 障碍物3位置 [x, y, z]
];

% 定义TGA参数
num_trees = 50; % 树木数量
max_iterations = 100; % 最大迭代次数
step_size = 1; % 步长

% 定义适应度函数
fitness_func = @(x) objective_func(x, start_point, target_point, city_map, obstacles);

% 初始化树木
trees = unifrnd(0, 1, num_trees, 3); % 初始位置随机分布
best_solution = [];
best_fitness = Inf;

% 迭代优化
for iteration = 1:max_iterations
% 计算适应度值
fitness_values = fitness_func(trees);

% 更新最优解
[min_fitness, min_index] = min(fitness_values);
if min_fitness < best_fitnessbest_solution = trees(min_index, :);best_fitness = min_fitness;
end% 生长新树
new_trees = zeros(num_trees, 3);

end% 更新树木
