array-memoize: Memoization combinators using arrays for finite sub-domains of functions
Memoization combinators are great for providing high-performance Haskell programs, but they can be even faster if memoization is performed on a finite, discrete domain since an array can then be used to store results.
This package provides various combinators for doing just this, including also combinators for quanitzing and discretizing Float/Double-valued functions.
fib' :: (Int -> Int) -> Int -> Int fib' _ 0 = 1 fib' _ 1 = 1 fib' rec n = rec (n - 1) + rec (n - 2) fib :: Int -> Int fib = arrayMemoFix (0, 1000) fib'
