function elites = select_elites(population, F_combine, population_size, combine_crowding_distance) elites = []; % 从前沿层数低到高依次选取精英个体 i = 1; front = F_combine{1}; while size(elites,1) < population_size elites = [elites; population(front,:)]; i = i+1; front = F_combine{i}; end if size(elites,1) > population_size b = size(elites,1) - population_size; [~,index] =sort(combine_crowding_distance(front)); index_sel = index(1:b); elites(index_sel,:)=[]; end修改这段代码，令其完成当size(elites,1) = population_size时跳出循环

修改后的代码如下：

function elites = select_elites(population, F_combine, population_size, combine_crowding_distance)
    elites = []; % 从前沿层数低到高依次选取精英个体
    i = 1;
    front = F_combine{1};
    
    while size(elites,1) < population_size
        elites = [elites; population(front,:)];
        i = i+1;
        
        if i > length(F_combine) % 如果已经到达最后一个前沿层，则跳出循环
            break;
        end
        
        front = F_combine{i};
    end
    
    if size(elites,1) > population_size
        b = size(elites,1) - population_size;
        [~,index] = sort(combine_crowding_distance(front));
        index_sel = index(1:b);
        elites(index_sel,:) = [];
    end
end

修改后，当 `size(elites,1) = population_size` 时，程序会直接跳出循环，不再继续选取精英个体。
