Subject: Re: [Help-glpk] Objective function defined with max, min.

Andrew & Michael,
Thanks a lot for the advice. I implemented binary variables, for f(x) =
max(x, 0). It seems to give a correct result, but works extremely slower
than LP problem. It takes like 10s for have a few dozen points with
binary variables, and I don't know how long for real problem with
hundreds of points.
How?
Details matter.
If you used a big-M method, how did you choose M?
