Real-Time Systems Optimization with Black-box Constraints and Hybrid Variables
CoRR(2024)
摘要
When optimizing real-time systems, designers often face a challenging problem
where the schedulability constraints are non-convex, non-continuous, or lack an
analytical form to understand their properties. Although the optimization
framework NORTH proposed in previous work is general (it works with arbitrary
schedulability analysis) and scalable, it can only handle problems with
continuous variables, which limits its application. In this paper, we extend
the applications of the framework NORTH to problems with a hybrid of continuous
and discrete variables. This is achieved in a coordinate-descent method, where
the continuous and discrete variables are optimized separately during
iterations. The new framework, NORTH+, improves around 20
than NORTH in experiments.
