%执行变异操作 children = mutation(children, mutation_rate);中的mutation函数的matlab代码示例

下面是一个可能的mutation函数示例：

function mutated_population = mutation(population, mutation_rate)
% MUTATION function performs mutation on the population
% Input:
%   - population: the current population [n_individuals x n_genes]
%   - mutation_rate: the probability of mutation
% Output:
%   - mutated_population: the population after mutation [n_individuals x n_genes]

[n_individuals, n_genes] = size(population);

mutated_population = population;

for i = 1:n_individuals
    for j = 1:n_genes
        if rand() < mutation_rate
            % mutate gene with random value between 0 and 1
            mutated_population(i,j) = rand();
        end
    end
end

end

这个mutation函数遍历所有个体和基因，并使用给定的mutation_rate概率对基因进行突变。在此示例中，我们将突变后的基因设置为0到1之间的随机值。
