Hi All,
I'm a new user of both Cplex and Glpsol, and i'm currently facing a
strange problem which you guys might know how to go through. I want to
convert a MathProg file into cplex formulation so that i can solve it
faster.
I use the simple command : glpsol -m model.mod -d data.dat --check
--wcpxlp model.lp which works fine.
The problem is that in model.lp, my binary variables from model.mod are
not defined as binary variables but with bounds such that : 0 <= x(1,1)
<= 1 and as Generals x(1,1).
My question is : Is there a way to automatically convert integer variables
from model.mod into BINARY variables in model.lp ? Indeed, i could remove
the bounds and define the variables as BINARY and not Generals but i would
have a lot of manipulations to do as i've got lots of benchs
More over, i get the feeling that this would make my PLNE easier to solve.
Many Thanks,
Regards,
- Sébastien M
