Although the self-adaptability of systems has been studied in a wide range of disciplines, from biology to robotics, only recently has the software engineering community recognized its key role in enabling the development of self-adaptive systems that are able to adapt to internal faults, changing requirements, and evolving environments. The 15 carefully reviewed papers included in this state-of-the-art survey were presented at the International Seminar on Software Engineering for Self-Adaptive Systems , held in Dagstuhl Castle, Germany, in October 2010. Continuing the course of the first book of the series on Software Engineering for Self-Adaptive Systems the collection of papers in this second volume comprises a research roadmap accompanied by four elaborating working group papers. Next there are two parts - with three papers each - entitled Requirements and Policies and Design Issues ; part four of the book contains four papers covering a wide range of Applications .
