I’m trying to solve the modeling of a linear programming exercise in Lingo and every time I have the software compile the code I get the error code:
11. INVALID INPUT. SYNTAX ERROR HAS OCCURRED.
However, everything you typed seems to be correct and I can’t find the error. I wonder if the problem is in my modeling or if I need to change some configuration so that everything works properly.
The modeling I’m referring to is the following:
MIN = x1 + x2 + x3
117/100*10^-5*x1 + 10^-5*x2 + 8*10^-6*x3 <= 1;
4*10^(6)*117/100*10^(-5)*x1 + 4*10^(6)*10^(-5)*x2 + 5*10^(6)*8*10^(-6)*x3 >= 25000000;
2*10^(6)*117/100*10^(-5)*x1 + 5*10^(6)*10^(-5)*x2 + 5*10^(6)*8*10^(-6)*x3 >= 20000000;
Some variations have been tried, such as:
MIN x1 + x2 + x3
or,
1.17 ao invés de usar 117/100
however, none of them solved
