Hello Cihan,

numbers in GLPK are of type double. Hence the highest number that can be specified will be around 1.7E308 on an X86 platform.

When using a big M approach, M should be choses as small as possible to avoid scaling problems. Hence a good choice of M is problem specific.

Best regards

Xypron
