I don't use functions glp_read_lp or glp_read_cpxlp.
And, I use GLP_FX (not GLP_DB) to fix bounds for the first variable.
So, I don't understand.
And, when I use lpx_write_cpxlp, I obtain this result.
The problem is that variables aren't integer and the first variable bound is
displayed as 1 <

This is not necessary, because glp_read_lp correctly set the types
of variables having identical lower and upper bounds to GLP_FX.

Hi,
I have a problem for integer variables with a lower bound equal at upper
bound.
I obtain this error message:
lpx_intopt: column 1 has incorrect bounds
My problem is:
PROBLEM: spConf_ whose formulation ref number is 1
Minimize
Objectif: -11.6667 Yi0_copy -11.6667 Yi1_copy -5 Yi2_copy
-5
