Query: Lifelong Dynamic Optimization for Self-Adaptive Systems: Fact or
  Fiction?   When faced with changing environment, highly configurable software systems
need to dynamically search for promising adaptation plan that keeps the best
possible performance, e.g., higher throughput or smaller latency -- a typical
planning problem for self-adaptive systems (SASs). However, given the rugged
and complex search landscape with multiple local optima, such a SAS planning is
challenging especially in dynamic environments. In this paper, we propose
LiDOS, a lifelong dynamic optimization framework for SAS planning. What makes
LiDOS unique is that to handle the "dynamic", we formulate the SAS planning as
a multi-modal optimization problem, aiming to preserve the useful information
for better dealing with the local optima issue under dynamic environment
changes. This differs from existing planners in that the "dynamic" is not
explicitly handled during the search process in planning. As such, the search
and planning in LiDOS run continuously over the lifetime of SAS, terminating
only when it is taken offline or the search space has been covered under an
environment.
  Experimental results on three real-world SASs show that the concept of
explicitly handling dynamic as part of the search in the SAS planning is
effective, as LiDOS outperforms its stationary counterpart overall with up to
10x improvement. It also achieves better results in general over
state-of-the-art planners and with 1.4x to 10x speedup on generating promising
adaptation plans.
