strength reduction

   Also found in: Wikipedia 0.01 sec.
strength reduction - An optimisation where a function of some systematically changing variable is calculated more efficiently by using previous values of the function. In a procedural language this would apply to an expression involving a loop variable and in a declarative language it would apply to the argument of a recursive function. E.g.

f x = ... (2**x) ... (f (x+1)) ...

==>

f x = f' x (2**x) where f ' x z = ... z ... (f' (x+1) 2*z) ...

Here the expensive operation (2**x) has been replaced by the cheaper 2*z in the recursive function f'. This maintains the invariant that z = 2**x for any call to f'.
