Genetic programming (GP) — the application of evolutionary computing techniques to the creation of computer programs — has been a key topic in computational intelligence in the last couple of decades. In the last few years a rising topic in GP has been the use of semantic methods. The aim of this is to provide a way of exploring the input-output behaviour of programs, which is ultimately what matters for problem solving. This new approach has produced substantially better results on a number of problems, both benchmark problems and real-world applications and, has been grounded in a body of theory, which also informs algorithm design and builds interesting links with theoretical computer science and search-based software engineering. There are a number of research groups that are active in this area around the world. This is a growing research area, with an increasing number of publications each year.
This workshop is the second edition after the highly successful event we organized at PPSN’14, which attracted 30+ participants for an entire day. This time it will be collocated with GECCO'14, the premiere event on evolutionary computation. It provides both an opportunity to consolidate and extend work in this growing area, and to inform a wider group of people about this growing area of work. We can see these semantic methods being important in other areas of computational intelligence and machine learning, and so this provides a good opportunity for a broader set of conference participants to learn about this growth area.
The main goal of the workshop is to foster discussions rather than present finished work. Researchers working in GP and other branches of evolutionary computation are strongly encouraged to participate.
All aspects of research related to semantic aspects in GP will be considered, including:
