Parallel Hybrid Metaheuristics: on performance and scale

Abstract:

Metaheuristics are a significant approach for applying artificial intelligence to large search spaces. We present PHYSH, a framework to ease the design and implementation of hybrid metaheuristics via cooperative parallelism.

With this framework, the user only needs encode each of the desired metaheuristics and may rely on PHYSH for parallelisation, cooperation and hybridisation. PHYSH supports the combination of population-based and single-solution metaheuristics and enables the user to control the tradeoff between intensification and diversification.

We present experimental evidence that PHYSH brings significant improvements over competing approaches.
