  AHD-CMA is a hybrid metaheuristic pairing the Dhole Optimization
  Algorithm (DOA) with CMA-ES via a probe-then-lock phase controller.
  This repository contains the full implementation, the official
  CEC-2022 (opfunu) benchmark harness, the LoRA hyperparameter-tuning
  case study, and all scripts to reproduce the figures and tables of
  the paper, together with the released result files.
