TL;DR: In this paper, the authors present the state-of-the-art and identify research challenges when developing, deploying and managing self-adaptive software systems, focusing on four essential topics of selfadaptation: design space for selfadaptive solutions, software engineering processes, from centralized to decentralized control, and practical run-time verification & validation.

TL;DR: It is argued that traditional approaches to handling resource variability in applications are inadequate, and an alternative architectural framework is described that is better matched to the needs of ubiquitous computing.

TL;DR: Focusing on the engineering issues of self-adaptation in the presence of heterogeneous platforms, legacy applications, mobile users, and resource variable environments, a new approach based on the following key ideas is described.

TL;DR: This paper shows how to provide a shared infrastructure that automates configuration decisions given a specification of the user's task and validates this approach both analytically and by applying it to a representative scenario.

TL;DR: The SASSY (Self-architecting Software Systems) framework automatically generates candidate software architectures and selects the one that best serves stakeholder-defined, scenario-based quality-of-service (QoS) goals, which lets domain experts concentrate on functional and QoS requirements.
