Please do cvs update at .../snap/nonagent/mspec2marbles2. You can run "sh snaptest.sh" at .../snap/runs/2002-03-14-513-multiple-pits.

Unfortunately, our current AbstractActivity that we use for all scheduling only supports a single contiguous interval for booking pilots, and we can't book the pilots through the night because that would trigger a crew day violation. Thus, I'm widening the AbstractActivity from "Interval time" to "MtMergingIntervals times". The widened schedule will still not support interleaving activities (which is fine in the SNAP domain at the moment, but we'll need to widen further some day). This will affect SNAP, Marbles 1 solvers, and Marbles 2 solvers; I will adjust all of the code to thew new structure. Just a heads-up.

One for brief and one for performance interval? The "and" logic in REQ would make sure that both activities succeed or both are canceled.

Concretely, this means if anyone of you (Seong-Bin, Alejandro, Min, Donghan) checks broken Marbles2 code into CVS this will affect the SNAP team immediately (and you'll hear about it...). So, what I suggest is that before a check-in, you do the following: (a) You say "make fresh" (Seong-Bin: in dce/snap, other three: in dce/marbles2 or dce/marbleplayground) before you say "cvs commit". (b) Say "make cvsupdate" and make sure you see no question marks for any files you added. If you do, say "cvs add" for those files. (c) Say "cvs commit" for all directories you worked in. (d) Say "make cvsupdate" again, and make sure you don't see any files marked with "M" or "?". Let's give it a shot.
