"Logic programming"[0] is what I've always heard this stuff called. I was introduced to it with Prolog.

"Declarative programming"[1] is kind of a superset of logic programming, which may or may not be the aspect that piques your interest.

"Constraint programming"[2] and "Constraint logic programming"[3] are also a perspective on it.
