With increasing reliance on multi-core parallel computing performance is evermore
dominated by interprocessor data communication typically provided by last level cache …

Performance is one of the most important qualities of software. Several techniques have thus
been proposed to improve it, such as program transformations, optimisation of software …

It is 30 years since John R. Koza published “Jaws”, the first book on genetic programming
[Genetic Programming: On the Programming of Computers by Means of Natural Selection …

Genetic improvement (GI) improves both functional properties of software, such as bug
repair, and non-functional properties, such as execution time, energy consumption, or …

Large arithmetic expressions are dissipative: they lose information and are robust to
perturbations. Lack of conservation gives resilience to fluc-tuations. The limited precision of …

Using the language independent genetic improvement tool MAGPIE (Machine Automated
General Performance Improvement via Evolution of software) and logarithmic sampling, we …

Emergent software systems are assembled from a collection of small code blocks, where
some of those blocks have alternative implementation variants; they optimise at run-time by …

Following the formal presentations, which included keynotes by Prof. Myra B. Cohen of Iowa
State University and Dr. Sebastian Baltes of SAP as well as six papers (which are recorded …

Writing source code is a challenging task, requiring the understanding of complex concepts,
algorithms and programming paradigms. This task becomes increasingly challenging when …
