New this year: Special track on Artificial Neural Network applied to Music, Sound, Art and Design
LEONARDO Special Section
Authors of selected papers will be invited to submit expanded versions of their work for a planned special section on Evolutionary Art of the MIT Press journal "Leonardo".

Following the success of previous events and the importance of the field of evolutionary and biologically inspired (artificial neural network, swarm, alife) music, sound, art and design, evomusart has become an evo* conference with independent proceedings since 2012. Thus, evomusart 2014 is the twelfth European Event and the third International Conference on Evolutionary and Biologically Inspired Music, Sound, Art and Design.

The use of biologically inspired techniques for the development of artistic systems is a recent, exciting and significant area of research. There is a growing interest in the application of these techniques in fields such as: visual art and music generation, analysis, and interpretation; sound synthesis; architecture; video; poetry; design; and other creative tasks.

The main goal of evomusart 2014 is to bring together researchers who are using biologically inspired computer techniques for artistic tasks, providing the opportunity to promote, present and discuss ongoing work in the area.

The event will be held in April, 2014 in Granada, Spain, as
part of the evo* event.

An Indirect Fitness Scheme for Automated Evolution of Aesthetic Images Gary Greenfield
Recently, the question of whether artifacts obtained from a generative art system can be judged as creative based on the characteristics of their offspring has received considerable attention. Here, we focus on the question of whether aesthetic images can be evolved by considering characteristics of their offspring. We introduce a formal model for designing fitness functions for use in automated evolution of aesthetic images whereby genotypes are evaluated relative to certain characteristics of their offspring. We describe the results of an experiment using such an indirect fitness scheme that promotes offspring diversity in order to help select for parent phenotypes with desired symmetry and complexity properties. We use as our image generation platform a variant of the Sims' classical Evolving Expressions generative art system. 

Genomic: Evolving Sound Treatments Using Genetic Algorithms  Thomas Stoll
There are many systems for the evolution of creative musical material, that create and/or manipulate musical score data or synthesis parameters with a variety of techniques. This paper aims to add the technique of corpus-based sound sampling and processing to the list of applications used in conjunction with genetic algorithms. Genomic, a simple system for evolving sound treatment parameters, is presented, along with two simple use cases. Finally, a more complex process is outlined where sound treatment parameters are evolved and stored in a database with associated metadata for further organization and compositional use.

Size Does Not Matter: Evolving Parameters for a Cayley Graph Visualiser using 64 bits Miguel Nicolau, Dan Costelloe
In this paper, an Interactive Evolutionary system is described, which generates visually appealing 3D projections of mathematical constructs. This system uses a combination of the Grammatical Evolution paradigm and Jenn3d, a visualiser of Cayley graphs of finite Coxeter groups. A very compact representation is used for the genotype strings, using only 64 bits. The resulting visualisations, albeit somewhat restricted, still exhibit a large degree of complexity and evolvability, and are well representative of the domain.

Feature Construction using Genetic Programming for Classification of Images by Aesthetic Value Andrew Bishop, Vic Ciesielski and Karen Trist
Classification or rating of images according to their aesthetic quality has applications in areas such as image search, compression and photography. It requires the construction of features that are predictive of the aesthetic quality of an image. Constructing features manually for aesthetics prediction is challenging. We propose an approach to improve on manually designed features by constructing them using genetic programming and image processing operations implemented using OpenCV. We show that this approach can produce features that perform well. Classification accuracies of up to 81% on photographs and 92% on computationally generated images have been achieved. Both of these results significantly improve on existing manually designed features.

A complexity approach for identifying aesthetic composite landscapes  Adrian Carballal, Rebeca Perez, Antonino Santos and Luz Castro
The present paper describes a series of features related to complexity which may allow to estimate the complexity of an image as a whole, of all the elements integrating it and of those which are its focus of attention. Using a neural network to create a classifier based on those features an accuracy over 85% in an aesthetic composition binary classification task is achieved. The obtained network seems to be useful for the purpose of assessing the Aesthetic Composition of landscapes. It could be used as part of a media device for facilitating the creation of images or videos with a more professional aesthetic composition.

Authorship and aesthetics experiments. Comparison of results between Human and Computational Systems Luz Castro, Rebeca Perez, Antonino Santos and Adrian Carballal
This paper presents the results of two experiments comparing the functioning of a computational system and a group of humans when performing tasks related to art and aesthetics. The first experiment consists of the identification of a painting, while the second one uses the Maitland Graves's aesthetic appreciation test. The proposed system employs a series of metrics based on complexity estimators and low level features. These metrics feed a learning system using neural networks. The computational approach achieves similar results to those achieved by humans, thus suggesting that the system captures some of the artistic style and aesthetics features which are relevant to the experiments performed.

Probabilistic Decision Making for Interactive Evolution with Sensitivity Analysis (EvoMUSART best paper candidate) Jonathan Eisenmann, Matthew Lewis and Rick Parent
Recent research in the area of evolutionary algorithms and interactive design tools for ideation has investigated how sensitivity analysis can be used to enable region-of-interest selection on design candidates. Even though it provides more precise control over the evolutionary search to the designer, the existing methodology for this enhancement to evolutionary algorithms does not make full use of the information provided by sensitivity analysis and may lead to premature convergence. In this paper, we describe the shortcomings of previous research on this topic and introduce an approach that mitigates the problem of early convergence. A discussion of the trade-offs of different approaches to sensitivity analysis is provided as well as a demonstration of this new technique on a parametric model built for character design ideation.

An Interface for Fitness Function Design
(EvoMUSART best paper candidate) Penousal Machado, Tiago Martins, Hugo Amaro and Pedro H. Abreu
Fitness assignment is one of the biggest challenges in evolutionary art. Interactive evolutionary computation approaches put a significant burden on the user, leading to human fatigue. On the other hand, autonomous evolutionary art systems usually fail to give the users the opportunity to express and convey their artistic goals and preferences. Our approach empowers the users by allowing them to express their intentions through the design of fitness functions. We present a novel responsive interface for designing fitness function in the scope of evolutionary ant paintings. Once the evolutionary runs are concluded, further control is given to the users by allowing them to specify the rendering details of selected pieces. The analysis of the experimental results highlights how fitness function design influences the outcomes of the evolutionary runs, conveying the intentions of the user and enabling the evolution of a wide variety of images.

Evolving an Aircraft Using a Parametric Design System  Jonathan Byrne, Philip Cardiff, Anthony Brabazon and Michael O'Neill
Traditional CAD tools generate a static solution to a design problem. Parametric systems allow the user to explore many variations on that design theme. Such systems make the computer a generative design tool and are already used extensively as a rapid prototyping technique in architecture and aeronautics. Combining a design generation tool with an evolutionary algorithm provides a methodology for optimising designs. This works uses NASA's parametric aircraft design tool (OpenVSP) and an evolutionary algorithm to evolve a range of aircraft that maximise lift and reduce drag while remaining within the framework of the original design. Our approach allows the designer to automatically optimise their chosen design and to generate models with improved aerodynamic efficiency.

A Novelty Search and Power-Law-Based Genetic Algorithm for Exploring Harmonic Spaces in J.S. Bach Chorales Bill Manaris, David Johnson and Yiorgos Vassilandonakis
We present a novel, real-time system, called Harmonic Navigator, for exploring the harmonic space in J.S. Bach Chorales. This corpus-based environment explores trajectories through harmonic space.  It supports visual exploration and navigation of harmonic transition probabilities through interactive gesture control. These probabilities are computed from musical corpora (in MIDI format).  Herein we utilize the 371 J.S. Bach Chorales of the Riemenschneider edition. Our system utilizes a hybrid novelty search approach combined with power-law metrics for evaluating fitness of individuals, as a search termination criterion. We explore how novelty search can aid in the discovery of new harmonic progressions through this space as represented by a Markov model capturing probabilities of transitions between harmonies.  Our results demonstrate that the 371 Bach Chorale harmonic space is rich with novel aesthetic possibilities, possibilities that the grand master himself never realized.

Balancing Act: variation and utility in Evolutionary Art Jon McCormack

Evolutionary Art typically involves a tradeoff between the size and flexibility of genotype space and its mapping to an expressive phenotype space. Ideally we would like a genotypic representation that is terse but expressive, that is, we want to maximise the useful variations the genotype is capable of expressing in phenotype space. Terseness is necessary to minimise the size of the overall search space, and expressiveness can be loosely interpreted as phenotypes that are useful (of high fitness) and diverse (in feature space). In this paper I describe a system that attempts to maximise this ratio between terseness and expressiveness. The system uses a binary string up to any maximum length as the genotype. The genotype string is interpreted as building instructions for a graph, similar to the cellular programming techniques used to evolve artificial neural networks. The graph is then interpreted as a form-building automaton that can construct animated 3-dimensional forms of arbitrary complexity. In the test case the requirement for expressiveness is that the resultant form must have recognisable biomorphic properties and that every possible genotype must fulfil this condition. After much experimentation, a number of constraints in the mapping technique were devised to satisfy this condition. These include a special set of geometric building operators that take into account morphological properties of the generated form. These methods were used in the evolutionary artwork 'Codeform', developed for the Ars Electronica museum. The work generated evolved virtual creatures based on genomes acquired from the QR codes on museum visitor's entry tickets.
