Increasingly, software systems should self-adapt to satisfy new requirements and
environmental conditions that may arise after deployment. Due to their high complexity,
adaptive programs are difficult to specify, design, verify, and validate. Moreover, the current
lack of reusable design expertise that can be leveraged from one adaptive system to another
further exacerbates the problem. We studied over thirty adaptation-related research and
project implementations available from the literature and open sources to harvest adaptation …

As applications grow in size and complexity, and computing infrastructure continues to
evolve, it becomes increasingly difficult to build a system that satisfies all requirements and
constraints that might arise during its lifetime. As a result, there is an increasing need for the
software to adapt to new requirements and environmental conditions after the software has
been deployed. Due to their high complexity, adaptive programs are generally difficult to
specify, design, verify, and validate. In addition, the current lack of reusable design expertise …
