Question

我尝试遵循PlatEMO的主要教程，但未能编译。我试图修改一个已经存在的函数，但是出现了太多错误。

这是我已经尝试过的代码：

classdef counster < PROBLEM
    %HELP COUNSTER


    methods
        %% Initialization

        function obj = counster()
            obj.Global.M = 2;
             if isempty(obj.Global.D)
                obj.Global.D = 2;
             end
            obj.Global.lower    =[0,zeros(1,obj.Global.D-1)-2];
            obj.Global.upper    = [1,zeros(1,obj.Global.D-1)+2];
            obj.Global.encoding = 'real';
        end
         %% Calculate objective values
        function PopObj = CalObj(obj,X)
            PopObj(:,1) = X(1);
            PopObj(:,2) = (1 + X(2))/X(1);
        end
        %% Calculate constraint violations
        function PopCon = CalCon(obj,X)
            PopCon(:,1)=-9*X(1)-X(2)+6;
            PopCon(:,2)= -9*X(1)-X(2)+1;
        end
    end
end

这是内置函数正常运行的示例：

classdef CF4 < PROBLEM
% <problem> <CF>
% Constrained benchmark MOP

            obj.Global.M = 2;

            h           = Y.^2;

            PopObj(:,2) = 1-X(:,1) + sum(h(:,J2),2);
        end

        end
        %% Sample reference points on Pareto front
        function P = PF(obj,N)
            P(:,1) = (0:1/(N-1):1)';

            temp2  = 0.75<P(:,1);
            P(temp1,2) = -0.5*P(temp1,1)+3/4;
            P(temp2,2) = 1 - P(temp2,1)+0.125;
        end
    end
end

>> main('-algorithm',@MOPSO,'-problem',@counster,'-N',200,'-M',10);

这意味着要绘制一个律师问题的前锋，但我知道了：

索引超出矩阵尺寸。

INDIVIDUAL中的错误（第79行）
                      obj(i).obj = Objs(i,:);

GLOBAL/Initialization中的错误（第151行）
              Population = INDIVIDUAL(obj.problem.Init(N));

MOPSO中的错误（第23行）
      Population = Global.Initialization();

GLOBAL/Start中的错误（第120行）
                      obj.algorithm(obj);

main中的错误（第62行）
              Global.Start();

如何使用PlatEMO优化新的测试问题？
