Adaptive Strategy Design Pattern

According to a definition found in the summary of the Workshop on Adaptable and Adaptive Software[LL95]: “A program is called adaptive if it changes its behaviour automatically according to its context”. Within this context, we restrict our research domain to the automatic runtime adaptation of existing behaviours. In this paper, we propose an Adaptive Strategy Design Pattern that can be used to analyze or design self-adaptive systems. It makes the significant components usually involved in a self-adaptive system explicit, and studies their interactions. We show how the components participate in the adaptation process, and characterize some of their properties.
