Computing Dictionary 

 Definition:   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 NewtonRaphson 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_xx) > epsilon); Iteration can be expressed in functional languages using recursion: solve x n = if abs(new_xx) > epsilon
then solve new_x n
else new_x
where new_x = 0.5 * (x + n/x)
solve n/2 n
