`Brief' I can do. The workshop and the open-source software session
were well-attended. We could have used a few more people at the
User's Group meeting. Of the people that talked to me after sessions, two
questions stick in my mind, in the `whatever' category:
* ``How do I know which cuts to use for my application (scheduling)?''
* ''How can I pull an arbitrary leaf off the sbb search tree?''
I think I can now answer the second question (a mixture of brute
force and deception should do the trick). `Use BCP' might be a better
I'm sure the answer to the first question is out there in the
scheduling literature, but it's not at the front of my brain. More
specifically, I wish I had some rules of thumb, along the lines of ``Analysis
of the polyhedron defined by your constraint system says you should use cuts
X, Y, and Q.'' A proactive approach, rather than reactive. Then again, the
cost of analysis might well outweigh the cost of generating a few cuts to see
if they're effective.
