Hi David and Alex,
Thanks for your replies! I'm having trouble communicating it, and the underspecifiedness doesn't help. Perhaps that just means I don't really understand the problem. Please let me know if any particular parts are hazy. What we *really* care about is getting people to the conference that otherwise wouldn't. If we have to pick between people with a high score (say, a speaker who is also a student) and someone with a low score (someone who doesn't really appear to be very serious about attending let alone contributing), we'd pick the high scoring person. When I say score, it's one of the functions in the source file I linked. Think scalar product; it's a weight vector times ((apply comp fs) person). I'm flexible as to what that score looks like, but it'd be nice if there are tweakable values that map directly to real-life concepts; e.g. I can tell that we're valuing open source contributions twice as heavily as studenthood. I'm having trouble conveying more details without having to explain it in terms of one particular model. Since I've done integer programming and constraint programming before, I'll do that. Please don't interpret that as a bias against core.logic and its ilk :-) Since we're optimizing for attendance weighted by score, we're minimizing the sum of (* -1 score) of all the people not attending, subject to the sum of scores of all the people that *are* attending being less than or equal to the budget. That actually sounds like something that shouldn't be too hard to dump into a constraint solver. Perhaps I'll play with Loco tomorrow (it's late here) and compare the results. David: does the above clarify somewhat? Would sample data help? Thanks again! lvh -- You received this message because you are subscribed to the Google Groups "Clojure" group.
