lingo 求解最小值 目标 min 2*200/(1.5*sin(x1))+760/(1.5*sin(x2))
约束 2*(1.5*cos(x1)+1.47)*(200/(1.5*sin(x1)))+(1.5*cos(x2)+2.11)*(760/(1.5*sin(x2)))=1000;
pi/2 pi/2
约束 2*(1.5*cos(x1)+1.47)*(200/(1.5*sin(x1)))+(1.5*cos(x2)+2.11)*(760/(1.5*sin(x2)))=1000;

pi如果是表示π,请加pi=3.1415926;因为lingo中没有表示π的常量
min=2*200/(1.5*@sin(x1))+760/(1.5*@sin(x2));
2*(1.5*@cos(x1)+1.47)*(200/(1.5*@sin(x1)))+(1.5*@cos(x2)+2.11)*(760/(1.5*@sin(x2)))=1000;

lingo求解min=x1^2+x1*x2+x2^2-60*x1-3*x2;结果错误
lingo软件求教max=1/2*x1*x2*@sin(x4)+1/2*x2*x3*@sin(120-x4);x4>0;
Lingo最优化问题用Lingo集合(循环)编程求解:min z=-x1^2-x2^2-x3^2-x4^2+x1+2*x
怎样在lingo里表示目标函数max{min{x1,x2},min{x3,x4},min{x5,x6}}
多目标LINGO,现有3个目标X1,X2,X3.希望MIN=X1; MIN=X2; MAX=X3 求教怎么解决?三者间的
证明sin(x1+x2)-sinx1=2sin(x2/2)cos(x1+x2/2)
LINGO min 45;(x1+x2) ST x1+x2>=1 x1
用LINGO软件求解非线性规划:max z=x1^2-x2 s.t.{x1^2+x2^2
函数周期题记函数x1,x2,.x中最小数为min{x1,x2,x3,.xn} 设函数f(x)=min{1+sinωx,1
记实数x1,x2,x3.xn,中最小数为min{X1,X2,.Xn},设函数f(x)=min{1+sinwx,1-sin
谁可以帮我改下lingo语句谢谢!目标函数min=3.585*X1+3.666*X2+3.705*X3+3.737*X4
