Public bug reported:
Inequality constraints and integer variables give clearly incorrect
results, which are not explicitly mentioned in the documentation.
For instance, trying to solve the following program in lp format:
min: x;
x > 0;
int x;
Results in:
Value of objective function: 0
Actual values of the variables:
x 0
Which is clearly incorrect.
The solution, which involves using some artificial boundaries such as "x >
0.00000001" instead of "x > 0", is NOT intuitive and nowhere mentioned in the
documentation. This is extremely frustrating for novice users.
If there are limitations which prevent lp_solve from correctly parsing
the given input program without having to add some residual value to
"0", then at least it should be mentioned in the documentation.
