Syntax problem when compiling modeling in Lingo

Question

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

Hello,

This question is tagged as MATLAB, but usually Matlab is not compiled (at least from the user’s point of view). If this is from Matlab, let’s go to comments:

MIN is another variable or function?

Are you wanting to get the values of the 3 equations and compare the result or is it a set of equations.

x1,x2 and x3 are symbolic variables or numerical variables?

I await comments.
