New MSC-CMA-ES algorithm enhances optimization with structure-aware restarts

By PulseAugur Editorial · [1 sources] ·

A new research paper introduces MSC-CMA-ES, a novel structure-aware restart strategy for the CMA-ES optimization algorithm. Unlike traditional methods that draw restarts uniformly, MSC-CMA-ES partitions search spaces into basins of attraction and seeds restarts with locally scaled parameters. This approach demonstrated superior performance on composition functions, achieving 2.7 times the target coverage of BIPOP-CMA-ES, and the best median error on basic functions, though at the cost of reduced deep-target coverage due to its focus on landscape discovery.

    MSC-CMA-ES: Structure-Aware Restarts for CMA-ES via Cyclic Nearest-Better Basin Discovery

    CMA-ES is, per run, a local optimizer; multimodal search relies on restart strategies such as IPOP and BIPOP, which draw every restart uniformly and reuse no information from previous evaluations. Multi-Start Clustering CMA-ES (MSC-CMA-ES) makes restarts structure-aware: in alter…
