Iteration

n.	1.	Recital or performance a second time; repetition. What needs this iteration, woman? - Shak.
	2.	(Computers) The execution of a statement or series of statements in a loop which is repeated in a computer program; as, at each iteration, the counter is incremented by 2.

Noun	1.	iteration - (computer science) a single execution of a set of instructions that are to be repeated; "the solution took hundreds of iterations" Synonyms: loop
	2.	iteration - (computer science) executing the same set of instructions a given number of times or until a specified result is obtained; "the solution is obtained by iteration" Synonyms: looping
	3.	iteration - doing or saying again; a repeated performance

(programming)

iteration - Repetition of a sequence of instructions. A fundamental part of many algorithms. Iteration is characterised by a set of initial conditions, an iterative step and a termination condition. A well known example of iteration in mathematics is Newton-Raphson iteration. Iteration in programs is expressed using loops, e.g. in C: new_x = n/2; do x = new_x; new_x = 0.5 * while (abs(new_x-x) > epsilon); Iteration can be expressed in functional languages using recursion: solve x n = if abs(new_x-x) > epsilon then solve new_x n else new_x where new_x = 0.5 * (x + n/x) solve n/2 n
