### 🚀 Performance (CPU) * Replaces `np.polyval` with a parallel Numba JIT function (`_calculate_ranks_numba`). * Replaces $O(N \log N)$ `np.argsort` with $O(N)$ `np.argpartition` in the GA loop. * Adds `numba` as a core dependency. ### 🧠 Robustness (Algorithm) * Implements Blend Crossover (BLX-$\alpha$) for better, extrapolative exploration. * Uses a hybrid selection model (top X% for crossover, 100% for mutation) to preserve root niches. * Adds `selection_percentile` and `blend_alpha` to `GA_Options` for tuning.
