Did anyone attempt to execute lpx_integer with more than 200 hundreds of integer variables?
My problem deals with about 10,000 integer variables. Any recommendation of what modification needs to be done in the lpx_integer routine to cater for 10,000 integer variables?
If your problem is a capacitated transhipment problem,
you're in like
If it's not and GLPK can't solve it,
look for more constraints or a better formulation.
