In other words, "no one but the night watchman is working at night". In that case, your conversion from actual time to finite integers can simply make the nonactive periods disappear from your model of the problem.
That is to say, if 4:59 PM on Monday corresponds to timeslot number #1389 in your finite domain encoding, then 9:00 AM on Tue might correspond to timeslot #1390. If not, then I think you will need "pre-emptive" scheduling techniques (and woe is you ;). -- [EMAIL PROTECTED] Vanderbilt University Nashville, TN USA _________________________________________________________________________________ mozart-users mailing list [email protected] http://www.mozart-oz.org/mailman/listinfo/mozart-users
