Abstract
Traditional evolutionary approaches to computer creativity focus on optimisation, that is they define some criteria that allows the ranking of individuals in a population in terms of their suitability for a particular task. The problem for creative applications is that creativity is rarely thought of as a single optimisation. For example, could you come up with an algorithm for ranking music or painting? The difficulty is that these broad categories are shifting and subjective: I might argue that Mozart is more musically creative than Lady Gaga, but others may disagree. Objective, fine-grained ranking of all possible music is impossible, even for humans. I will show how reconceptualising the exploration of a creative space using an “ecosystemic” approach can lead to more open and potentially creative possibilities. For explanatory purposes, I will use some successful examples that are simple enough to explain succinctly, yet still exhibit the features necessary to demonstrate the advantages of this approach.

Notes
- 1.
By my estimates, about 5×10−1444925 % for images of modest dimensions, far beyond astronomically small.
- 2.
By “generative mechanism” I am technically referring to the genotype and the mechanism that expresses it into a phenotype.
- 3.
The mechanism can include the ability to self-modify, change, or learn.
- 4.
We might think of “viable” as meaning being able to effectively express a living organism from a zygote or through mitosis of a parent cell. But this is problematic for many reasons, most of which are too tangential to the argument to list here.
- 5.
This issue is a topic of discussion in Chap. 4.

Danish biologist Eugen Warming is also attributed as the founder of the science of Ecology.
- 8.
Autotrophs, such as plants, produce organic substances from simpler inorganic substances, such as carbon dioxide; heterotrophs unable to perform such conversions, require organic substances as a source of energy.

Reminiscent of Kodak founder George Eastman’s famous tag line of 1888 for the Kodak No. 1 camera: “You press the button, we do the rest”.
