Abstract. The goal of this roadmap paper is to summarize the stateof-the-art and identify research challenges when developing, deploying and managing self-adaptive software systems. Instead of dealing with a wide range of topics associated with the field, we focus on four essential topics of self-adaptation: design space for self-adaptive solutions, software engineering processes for self-adaptive systems, from centralized to decentralized control, and practical run-time verification & validation for self-adaptive systems. For each topic, we present an overview, suggest future directions, and focus on selected challenges. This paper complements and extends a previous roadmap on software engineering for self-adaptive systems published in 2009 covering a different set of topics, and reflecting in part on the previous paper. This roadmap is one of the many results of the Dagstuhl Seminar 10431 on Software Engineering for Self-Adaptive Systems, which took place in October 2010.

A method and a corresponding tool is described which assist design recovery and program understanding by recognising instances of design patterns semi-automatically. The approach taken is specifically designed to overcome the existing scalability problems caused by many design and implementation variants of design pattern instances. Our approach is based on a new recognition algorithm which works incrementally rather than trying to analyse a possibly large software system in one pass without any human intervention. The new algorithm exploits domain and context knowledge given by a reverse engineer and by a special underlying data structure, namely a special form of an annotated abstract syntax graph. A comparative and quantitative evaluation of applying the approach to the Java AWT and JGL libraries is also given.

Mechatronics is an engineering discipline integrating the fields of mechanical engineering, electrical engineering and computer science. While the word "mechatronics" already has a long history, it is only the last ten years that we see their application all around us. Cars, CD players, washing machines, railways are all examples of mechatronic systems. The main characteristic (and driving force) of recent advances is the progressively tighter coupling of mechanic and electronic components with software. This makes software engineering (together with network technology) the main computer science discipline involved in mechatronics.In this paper we survey current developments and discuss future trends in mechatronics, in particular from a software engineering point of view. The future of mechatronics will specifically see a move towards a high degree of adaptibility and self-organisation. This poses new challenges on software engineering, especially on modelling, code generation and analysis. We exemplify existing as well as future strands by a collaborative research and development project of a mechatronic rail system from the University of Paderborn.Future of Software Engineering(FOSE'07) 0-7695-2829-5/07 $20.00
