I'm just getting started with logic programming, and it is entirely
possible I'm just approaching this incorrectly.
Is it possible to use dynamically generated goals in run* ?
For example,
(defrel grade person course g)
(fact grade 'Bob 'Algebra 'B)
(fact grade 'Bob 'Art 'C)
(fact grade 'John 'Algebra 'A)
(fact grade 'John 'Art 'A)
(fact grade 'Ricky 'Algebra 'D)
(fact grade 'Ricky 'Art 'A)
(def knowledge
{:course 'Algebra :g 'B})
(defn generate-goals [knowledge]
(map
(fn [{:keys [course g]}] (list 'grade 'person course g))
knowledge))
I want to do something like this (but valid clojure):
(run* [person]
~@(generate-goals knowledge))
It should give me back a list of people who match my current
knowledge. If I have more knowledge about the person, it will generate
more conditions, less knowledge fewer conditions. However, since run*
and run are macros, I can't apply them to a list. I can't splice in
because I'm not in a quotes list. Any ideas?
Thanks!
