302,define/memo doesn't save time for funs of arity > 1,clements@…,dherman,"It appears that define/memo is missing all of the time for functions of more than one argument.  Here's a version of fib that takes 2 (identical) arguments:


#lang racket

(require (planet dherman/memoize))

(define/memo (fib n1 n2)
  (if (<= n2 1) 1 (+ (fib (- n1 1) (- n2 1)) (fib (- n1 2) (- n2 2)))))

(time (fib 28 28))

This program runs faster without memoization; it appears that the cache check always misses.
