讲座概要
Many matching markets, such as ridesharing, online game matching, and in-stream video advertising, involve dynamic processes where users or customers arrive sequentially. A fundamental challenge in these platforms is the tradeoff between matching speed and quality. Faster matching reduces waiting time but may result in lower matching quality, while slower matching or matching only when the market is sufficiently dense can improve quality at the expense of increased waiting time. In this presentation, we propose a type of simple policy that achieves good performance across various scenarios and discuss its implications in practice.
