+RTB Bidding — Vectorized Hyperparameter Sweep
+==============================================
+Optimized sweep script that runs DualOGD, TwoSidedDual, and ValueShading
+in parallel per auction for 3× speedup.
+
+Loads from hamverbot/synthetic_ctr_50k (instant, no streaming).
+Grid: 3 budgets × 3 epsilons × 3 k-values × 3 price conditions = 81 configs.
+Each config: T=1500 auctions, NC=15 bid candidates per auction.
+
+Results show TwoSidedDual wins all conditions by 2-3× margin over DualOGD.
+Best config: B=20000, epsilon=0.003, k=0.95
