  abstract =     "Gentropy is a genetic programming system that evolves
                 two-dimensional procedural textures. It synthesizes
                 textures by combining mathematical and image
                 manipulation functions into formulas. A formula can be
                 re-evaluated with arbitrary texture-space coordinates,
                 to generate a new portion of the texture in texture
                 space. Most evolutionary art programs are interactive,
                 and require the user to repeatedly choose the best
                 images from a displayed generation. Gentropy uses an
                 unsupervised approach, where one or more target texture
                 image are supplied to the system, and represent the
                 desired texture features, such as colour, shape and
                 smoothness (contrast). Then, Gentropy evolves textures
                 independent of any further user involvement. The
                 evolved texture will not be identical to the target
                 texture, but rather, will exhibit characteristics
                 similar to it. When more than one texture is supplied
                 as a target, multiobjective feature analysis is
                 performed. These feature tests may be combined and
                 given different priorities during evaluation. It is
                 therefore possible to use several target images, each
                 with its own fitness function measuring particular
                 visual characteristics. Gentropy also permits the use
                 of multiple subpopulations, each of which may use its
                 own texture evaluation criteria and target texture.",
