Iteration. Iteration means the act of repeating a process with the aim of approaching a desired goal, target or result. Each repetition of the process is also called an iteration, and the results of one iteration are used as the starting point for the next iteration.
In curling, each round is called an end.. Curling games are  typically 8 ends (about 2 hours), though in regional/state,  national, and international competition (includingâ¦ the Olympics)  games are typically 10 ends, with a 5-minute break after the 5th  end (these games take 2.5 to 2.75 hours).
