[Help-glpk] Continuing search after time-out

[Pavel Klinov]

Hello,

If B&C search gets interrupted due to time-out and but then is run
again, does it start from scratch or is it able to continue from where
it stopped? Is there a way for it to store all the internal data
structures and continue?

Basically I want GLPK MIP solver  to give me the first "acceptable"
solution because sometimes it spends a lot of time searching "near"
the optimal one (as far as I see in the output). I guess the easiest
would be to use the callback function but this seems problematic since
I'm invoking GLPK via JNI (by using SWIG wrapper classes). Therefore I
set a time limit and then check if some solution has been found. If
not, I'd like to continue the search.

Thanks,
Pavel
