Optimization Algorithms for Guaranteed Delivery Advertising in Double‑11 Interactive Campaign

During Double‑11, the team created two specialized allocation algorithms—a brand‑score‑driven primal‑dual method for guaranteed‑downline contracts and a guarantee‑and‑balance flow‑re‑ranking approach for guaranteed‑non‑downline contracts—both using near‑line dual adjustments to meet contract volumes while boosting interaction depth, repeat visits, and browsing time.
