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).
The no-stem curl is placed directly on the base of the curl. It produces a tight, firm, long-lasting curl and allows minimum mobility. The half-stem curl permits medium movement; the curl (circle)is placed half off the base. It gives good control to the hair. The full-stem curl allows for the greatest mobility. The curl is placedcompletely off the base. The base may be a square, triangular, half-moon, or rectangular section, depending on the area of the head in which the full-stem curls are used.
