Dear Paul,
The number of integer variables is just one thing. I think i have a
MIP problem with less than 20 integer variables and glpsol would not
be able to solve it.
You should first improve and / or simplify your model rather than
change the code of the GLPK.
Or try a commercial solver such as ILOG CPLEX 10 and see what that can
do, it is not likely you could write a better (general purpose) solver
than that.
You should also try a higher version of GLPK because as far as i know
the MIP part was improved since 4.19.
Good luck,
Ali
