JANUS improves CMA-ES on 11-15 out of 16 BBOB functions across dimensions 30, 100, and 500 without requiring offline training

Under same-protocol comparisons, JANUS improves the CMA-ES host on \textbf{11--15/16} BBOB functions across $d\in\{30,100,500\}$. It also attains the best mean error on \textbf{13 of the 16} functions at $d{=}500$ in the complete NN-BBO/MetaBBO baseline comparison, with no training cost
