Hi,
I'm trying to solve a MIP problem from my java application using GLPK java interface, but I've a problem.
When I try to solve a problem with 37400 variables and 26925 constraints, I've this error:
........................................................................................................
* 54200:   objval =  1.974280191e+006   infeas =  5.631602624e-014 (0)
* 54398:   objval =  1.974137553e+006   infeas =  1.858620062e-012 (0)
OPTIMAL SOLUTION FOUND
Integer optimization begins...
+ 54398: mip =     not found yet >=              -inf        (1; 0)
umalloc: size = 24720512; malloc failed

How can I solve it?
Thanks
