The question is how do you solve the problem, and how do you obtain the solution.
When you make all these columns binary you have a Diophantine Equation. GLPK can solve these, though there are other ways which may be better.
GLPK will first solve it as a linear problem. It is then necessary to perform Integer Optimization.
Having done this there are different routines to obtain the integer optimal solution as opposed to the linear solution.

Do you obtain this value with GLPK.glp_get_mip_col_val ?
no with .glp_set_col_kind
Even if the type of variable is binary Lp give non integer value
Hello,
I have a very strange problem
I solve un Lp problem but the and the value of my variables are not ineger I got x(0,1)=0.2... even thaught when I print the type of my variables I got 3 coresponding to type binary( I got type to binary for all variables with GLPK.glp_set_col_kind(lp, i, GLPKConstants.GLP_BV)).
Can you tell my where the problem could be?
Thank you
Onor
