Re: [Help-glpk] GLPK just hangs

[Pavel Klinov]

Hello Xypron and others,

I have also observed that behaviour (asked here [1]). The performance
can degrade quite seriously unless I reload the problem instance. I'd
appreciate if someone could suggest another way of performing the same
steps (rounding or whatever) but w/o writing/reading data on disk.

Thanks,
Pavel
