求助检查一下lingo程序。急需使用，谢谢各位大侠了

Question

min=22*(x1*(5-x4)+0.5*x2*(5-x4)+x4*(x1+x2+x3)
x1>=0.4;
x1<=1
x3>=0.2;
x4-2*x3>=0;
1.67<=x1+x2+x3<=2.5;
22*x1*(5-x4)*(0.5*x1+x2+x3)+7.3*x2*x2*(5-x4)+11*x4*(x1+x2+x3)^2>213.5;
x1*(5-x4)+0.5*x2*(5-x4)+x4*(x1+x2+x3)>9.3;

Answer 1

min=22*x1*(5-x4)+0.5*x2*(5-x4)+x4*(x1+x2+x3);
x1>=0.4;
x1<=1;
x3>=0.2;
x4-2*x3>=0;
1.67<=x1+x2+x3;x1+x2+x3<=2.5;
22*x1*(5-x4)*(0.5*x1+x2+x3)+7.3*x2*x2*(5-x4)+11*x4*(x1+x2+x3)^2>213.5;
x1*(5-x4)+0.5*x2*(5-x4)+x4*(x1+x2+x3)>9.3;

结果是无界解

追问

我想知道程序错在哪点？数据我可以再修改的，能否把改正后的程序发给我。谢谢
