We study creating and breaking symmetry in digitally gen-erated artificial-life-based visual art. Therefore, an artificial swarm-based pattern-making system is used as a test bed. The patterns are generated algorithmically by emulating the collective feeding behavior of sand-bubbler crabs. Our fo-cus is on analyzing concepts and templates for incorporating symmetry and broken symmetry into the creation process of bioinspired art. All four types of two-dimensional symmetry defined by isometric maps are used to create images. Apart from treating geometric symmetry, we also consider color as an object of symmetric transformations. Color symmetry is realized as a color permutation consistent with the isometric maps. Therefore, color permutation groups have been de-signed which utilize mappings on a color wheel.

Fitness landscapes are an abstract way for describing the relationship between the genetically possible (genotype), the actually realized (phenotype) and the survival/reproduction success (fitness). In other words, fitness landscapes are about analysing and visualizing the relationships between genotypes, phenotypes and fitness, while these relationships lay at the centre of attempts to mathematically describe evolutionary processes and evolutionary dynamics.

The tutorial will cover the following topics.

• Principles and perspectives of fitness landscapes
• Examples of empirical and computational landscapes
• Topology, measures and problem hardness
• Coevolutionary and dynamic fitness landscapes
• Open questions and research topics
