[rules-dev] Miss Manners

[Mark Proctor]

I was wondering if anyone fancied having a go at improving Miss Manners 
to make it harder and less easy to cheat. The problem with manners at 
the moment is that it computes a large cross product, of which only one 
rule fires and the other activations are cancelled. What many engines do 
now is abuse the test by not calculating the full cross product and thus 
not doing all the work.

So I was thinking that first the amounts of data needs to be increased 
from say 128 guests to  512 guests. Then the problem needs to be made 
harder, and the full conflict set needs to be forced to be evalated. So 
maybe the first assign_seating rule is as normal where it just finds M/F 
pairs with same hobbies, but additionally we should have a scoring 
process so that those matched in the first phase then each must have 
some compatability score calculated against them and then the one with 
the best score is picked. Maybe people have other ways to improve the 
complexity of the test, both in adding more rules and more complex rules 
and more data.
