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>

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。
