[BCP] Confused about cut pool(s)

[Eric W Anderson]

Hi All,

I have a sort of general confusion about the way cuts are managed in BCP.   My
program generates cuts in the user-overridden generate_cuts_in_lp() function.
Is there a simple explanation of what data structures store cuts when, and how
the cuts get moved around between them? 

What especially confuses me is that after I generate those cuts, in subsequent
iterations they sometimes show up in the const BCP_vec<BCP_cut*>& cuts
parameter, and sometimes do not.  And when they don't, they still sometimes
(maybe always) show up in p->local_cuts.  The whole process is just very
unclear to me.

Any suggestions?  I've read the users' manual, the BAC document, and a lot
(though not all) of the BCP source code.  

Many thanks,
Eric
