in thread Looking for help with AI::Genetic and classroom scheduling

The problem is that the result is not simply a "valid" solution. I'm looking for a "best" solution. I know enough Prolog to code the search space for a valid solution, even using AI::Prolog (thanks Ovid!). What I need is for a way to move from a valid solution to a "better" solution, based on soft things like attendee preference, natural ordering of materials, and room size, after first matching hard things like a single-purpose room and a single-location instructor.

    Interestingly, I was just using AI::Prolog to try and solve this. Unfortunately, my attempted solution required math and I haven't built that in yet. Then I tried to build math logically for just the small problem set, but I hadn't yet defined the "is" primitive. Sigh. Unfortunately, the solutions at hand started getting difficult even when I used SWI-Prolog due to how exhaustive the search space is.

[Corion]: Whee! Germanys Grand Central Airport (for Berlin, re-scheduled for the thrid or fourth time, to open now in 2018) has just fired their technical lead
[ambrus]: Corion: Is their budget estimate four times the initial estimate yet? Was the construction late by six months already three months after they started?
[marto]: I'll believe it when I see it. That's been due for many years now :P
[marto]: oddly the last time I was there I saw a zeppelin in flight for the first time
[Corion]: ambrus: I don't know how far the budget estimate has been overrun yet
[Corion]: marto: Heh ;) No, you were likely at Tegel or Schönefeld, the new one ("BER") will be somewhat outside of Berlin ;)
[marto]: Corion Schoenfeld, but my friend has been telling me about this new airport for about 7-8 years now :P
[marto]: I doubt it even exists as a building site :P
