[Help-glpk] Command --objbnd

[ra134321]

Good Afternoon!
My name is Angelo and I make use of GLPK version 4-47. I have a doubt:
I want to provide for GLPK a bound for a objective function in a integer
problem, e.g., I have used the option
"--objbnd bound"
to offer a bound for a objective funcion of my problem. I already use the
comand "--minisat", as say the manual. However, when I run GUSEK the
following message appears:

"glp_intfeas1: column 1: non-binary non-fixed variable not allowed".

I have certainlly that the value bound used desn't make problem infeasible.
If this command doesn't possible, are there another way to provide a bound
for my integer problem? Could you tell me if there is more some command?
I am very greateful for the attention!
I wait for a answer!
Best regards,
Angelo.
