Editing Interactive evolutionary computation (section)

'''Interactive evolutionary computation''' (IEC) or '''aesthetic selection''' is a general term for methods of [[evolutionary computation]] that use human evaluation. Usually human evaluation is necessary when the form of [[fitness function]] is not known (for example, visual appeal or attractiveness; as in Dawkins, 1986<ref>{{cite book|author=Dawkins, R.|title=The Blind Watchmaker|publisher=Longman|year=1986|title-link=The Blind Watchmaker}}</ref>) or the result of optimization should fit a particular user preference (for example, taste of coffee or color set of the user interface).
