题目

我用lingo怎么只能解两个待定变量的多项式优化问题?
model:
sets:
C/1..80/:j;
endsets
data:
j=0.1,0.2,0.3,0.4,0.5,0.6,0.7,0.8,0.9,1.0,1.1,1.2,1.3,1.4,1.5,1.6,1.7,1.8,1.9,2.0,2.1,2.2,2.3,2.4,2.5,2.6,2.7,2.8,2.9,3.0,3.1,3.2,3.3,3.4,3.5,3.6,3.7,3.8,3.9,4.0,4.1,4.2,4.3,4.4,4.5,4.6,4.7,4.8,4.9,5.0,5.1,5.2,5.3,5.4,5.5,5.6,5.7,5.8,5.9,6.0,6.1,6.2,6.3,6.4,6.5,6.6,6.7,6.8,6.9,7.0,7.1,7.2,7.3,7.4,7.5,7.6,7.7,7.8,7.9,8.0;
enddata
min=@sum(C:(1+(2*a*j+3*b*j^2+4*c*j^3+5*d*j)^2)^0.5)*0.1;
(1+(16*a+3*b*8^2+4*c8^3+5*d*8^4))^2)^0.5=2.4;
(1+(16*a+24b^2+32c^3+5*d))^2)^0.5>6;

答案

你的程序这样改就没有语法错误了 model:sets:S/1..80/:j;endsetsdata:j=0.1,0.2,0.3,0.4,0.5,0.6,0.7,0.8,0.9,1.0,1.1,1.2,1.3,1.4,1.5,1.6,1.7,1.8,1.9,2.0,2.1,2.2,2.3,2.4,2.5,2.6,2.7,2.8,2.9,3.0,3.1,3.2,3.3,3...
