Hi Guys, I'm trying to memoize a fairly complicated double recursion, and it's blowing stack after not terribly many calls.
I've reduced the problem to a simple test case, summing from 1 to n : user=> (clojure-version) "1.5.1" user=> (def gauss-recurse (fn [n] (if (< n 1) 0 (+ n (gauss-recurse (dec n)))))) #'user/gauss-recurse user=> (gauss-recurse 3500) 6126750 user=> (def gauss-memoized (memoize (fn [n] (if (< n 1) 0 (+ n (gauss-memoized (dec n))))))) #'user/gauss-memoized user=> (gauss-memoized 160) StackOverflowError clojure.lang.RT.boundedLength (RT.java:1654) user=> Does anyone know why this would happen? Do I just have to give up on memoization and find another way to do dynamic programming? Cheers, John. -- -- You received this message because you are subscribed to the Google Groups "Clojure" group.
