Risk-Constrained Budget Pacing for Guaranteed Display Advertising

The paper introduces a percentile‑based risk‑constrained budget‑pacing algorithm for guaranteed‑delivery display ads that ties the pacing rate to the dual‑bidding factor’s percentile, preserving volume guarantees while preventing rapid spend bursts, using adaptive transforms, gradient clipping and stop‑loss controls, and demonstrates smoother spend and performance gains in large‑scale A/B tests.

Online Allocation Strategies for Guaranteed Display Advertising: Modeling, Distributed Solving, and Adaptive Pacing

The paper presents a guarantee‑based, distributed allocation framework for Alibaba’s off‑site brand contract ads that extends the SHALE algorithm with effect‑driven objectives and explicit over‑allocation constraints, solves dual variables via coordinate descent, and employs adaptive probability‑based pacing to meet volume guarantees while significantly boosting average CTR.
