The report summarises a general framework of CSN properties useful to specify target functions and fitness evaluation. Adopting aspects of this general framework, selected techniques for formal representation of target functions are introduced including some methods to facilitate specification. Aspects of CSN fitness measure and evaluation including distance and similarity measures complete the report.
Each of the sketched properties, techniques, and methods focuses on specific facets of interest in modelling and analysis of CSNs. Underlying theories, methodologies, and strategies are well established in the scientific community. We abstain from giving a detailed introduction into the background issues. Although some of the approaches mentioned before are known for several decades, new applications and areas of usage arise constantly. They aim to give inspirations and orientations for upcoming parts of the ESIGNET project. For further information, we refer to primary literature mentioned as well as to publications in the context of ESIGNET and its members.
