多约束拓扑优化MATLAB,matlab多目标优化问题，fgoalattain函数，将取值范围放的非常大，还出问题。...

约束条件：%%条件中有反正切函数和二次开方，会与这个有关系吗？

function [g,ceq]=YSTJ3(x)

g(1)=x(1)+x(2)-x(3)+100;

g(2)=200-((3^(0.5))/2)*x(5)-(x(1)+2*x(2))/2+x(3)+((3^(0.5))/4)*x(4);

g(3)=pi/6-atan((((3^(0.5))/2)*x(3))/(x(3)/2+x(1)+x(2)));

g(4)=1110-2*(3^(0.5))*(x(1)+x(2)+x(3));

g(5)=1060-2*(3^(0.5))*(x(1)+x(2)+x(3))+(3*(x(1)+x(2))/4+(3^(0.5))/2)*(x(3)^2-((x(1)+x(2))^2)/4)^(0.5);

g(6)=x(1)+x(2)+x(3)-410;

g(7)=350+(3*(x(1)+x(2))/4+(3^(0.5))/2)*(x(3)^2-((x(1)+x(2))^2)/4)^(0.5)-(3^(0.5))*(x(1)+x(2)+x(3));

目标函数：

function f=MBHS3(x)

f(1)=x(1);

f(2)=x(2);

f(3)=x(3);

f(4)=x(4);

f(5)=x(5);

执行函数：

x0=[70,70,250,90,500];

goal=[70,70,250,90,500];

w=goal;

lb=[0,0,0,0,0];

ub=[1000,1000,1000,1000,1000];

[xopt,fopt,c,d,e,f]=fgoalattain(@MBHS3,x0,goal,w,[],[],[],[],lb,ub,@YSTJ3)

运行结果：

Solver stopped prematurely.

fgoalattain stopped because it exceeded the function evaluation limit,

options.MaxFunEvals = 600 (the default value).
