[Help-glpk] optimality tolerance

[Duilio Foschi]

is there a way to set the optimality tolerance of a fairly large MIP
problem in GLPK ?

GLPK takes a VERY long time to solve it (no idea how long, I always
stopped the solver after many hours of running).

Is it trying to get the 1.0e-6 order best result ?

I would be content with a 1.0 order best result, provided that I get
it quickly (say <10hrs).

Thank you
