Programs using this can sometimes be sped up using memorization to store already-computed results or fully converted to iterative versions via dynamic programming.
This is governed by the lambda calculus, and LISP uses the "tail" version of this to eliminate the need for extra space on the call stack. Programs using this can sometimes be sped up using memorization to store already-computed results or fully converted to iterative versions via dynamic programming. The Ackerman function is defined using this, and successively larger solutions to the Towers of Hanoi problem can be built with this. FTP, name this concept in computer science in which a function is defined in terms of a smaller instance of itself.
