Web24 de jan. de 2024 · Applicative Order Reduction. Applicative-order reduction is the leftmost innermost reduction strategy. That is to say, you look for all the innermost redexes, and then pick the leftmost one and reduce that.

Given a term of the … WebApplicative vs Normal Order evaluation In applicative order execution (like regular Scheme), all procedure arguments are evaluated be-fore applying the procedure. In normal order execution, procedure arguments are evaluated after applying the procedure, and then only if the result is needed to complete the evaluation of the procedure.
