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``` Thesaurus Terms Related Terms: conduplication, copy, copying, critique, doubling, duplicate, duplication, dwelling upon, elaboration, gemination, going over, imitation, ingemination, practicing, reaffirmation, recap, recapitulation, recital, recountal, recounting, reduplication, rehash, rehearsal, reissue, reiteration, repetition, replication, reprint, reproduction, restatement, resume, retelling, review, summary, summing up, twinning
