Novel Aspects
• Classical: Arms assumed fixed over time– We gain and lose arms over time
• Some theoretical work by Whittle in 80’s; operations research
• Classical: Serving rule updated after each pull– We compute optimal design in batch mode
• Classical: Generally. CTR assumed stationary– We have highly dynamic, non-stationary CTRs
