输入：种群个体数量N
输出：分层的不同支配层{F_i}，i表示个体的支配层级

1: for j = 1: N
2: fitness_x_j = fitness_function(x_j); %计算个体x_j适应度
3: dominance_level(j) = 0; % 初始化支配层级
4: for g = 1: N
5: fitness_x_g = fitness_function(x_g); % 计算个体x_g适应度
6: if all(fitness_x_j <= fitness_x_g) && any (fitness_x_j < fitness_x_g)
7: dominance_level(j) = dominance_level(j)+1; % 更新支配层
8: end
