An image generated using an evolutionary algorithm

Evolutionary Art exploits the process of evolution to create an artwork which continually changes according to an evolutionary algorithm. Image created by me, using Imogenes by Harley Davis. ... In artificial intelligence, an evolutionary algorithm (EA) is a subset of evolutionary computation, a generic population-based metaheuristic optimization algorithm. ... In artificial intelligence, an evolutionary algorithm (EA) is a subset of evolutionary computation, a generic population-based metaheuristic optimization algorithm. ...


In common with natural selection and animal husbandry, the members of a population undergoing artificial evolution modify their form or behaviour over many reproductive generations in response to a selective regime. Darwins illustrations of beak variation in the finches of the Galápagos Islands, which hold 13 closely related species that differ most markedly in the shape of their beaks. ... In a draw in a mountainous region, a shepherd guides a flock of about 20 sheep amidst scrub and olive trees. ...


In interactive evolution the selective regime may be applied by the viewer explicitly by selecting individuals which are aesthtically pleasing. Alternatively a selection pressure can be generated implicitly, for example according to the length of time a viewer spends near a piece of evolving art. Interactive evolutionary computation (IEC) or Aesthetic Selection is a general term for methods of evolutionary computation that use human evaluation. ... Evolutionary pressure or selection pressure can be formalized as an external pressure applied to a process, thereby pushing that process in a distinct direction. ...


Equally, evolution may be employed as a mechanism for generating a dynamic world of adaptive individuals, in which the selection pressure is imposed by the program, and the viewer plays no role in selection, as in the Black Shoals project. Evolutionary pressure or selection pressure can be formalized as an external pressure applied to a process, thereby pushing that process in a distinct direction. ... Black Shoals is an artificial ecosystem linked to the real time dynamics of the stock market. ...

Denis Dutton on aesthetics and evolutionary psychology (4646 words)
Art was considered purely a determined product of culture, and there were as many kinds of art and artistic values as there were cultures.
Evolutionary psychology replaces the blank slate as a metaphor for mind with the Swiss army knife: the mind is a set of tools and capacities specifically adapted to important tasks and interests.
Works of art, especially of fine art, therefore engage the higher faculties, and the pleasures they afford are of a different order than sexual or gustatory sensations of pleasure.
APA Division 10 Web site: Articles (5953 words)
He discusses the mysteriousness of art and concludes that a reason for this obscurity is that the arts are not adaptive in the evolutionary sense.
The question of what determines good art is a complex and difficult one to answer, but taking an evolutionary point of view allows us to look at art from all times and cultures and the assessments of that art by peers and those of other times and cultures.
Conscious evaluation of the art work might result from unconscious emotional response evoked by the art, but the two processes are not the same and should be considered as two parts of aesthetic response.
