What you are trying to do is non-relational, and will only work when you put the non-relational pluso at the end.
You can obviously use the finite domain extensions to core.logic to accomplish this: (defn fd-pluso [t1 t2 s] (fd/eq (= s (+ t1 t2)))) (run* [q] (fresh [a] (fd/in q a (fd/interval Integer/MAX_VALUE)) (fd-pluso q 4 a) (== a 7))) => (3) I don't know how you achieve this result in core.logic without the finite domain support. -- -- You received this message because you are subscribed to the Google Groups "Clojure" group.
