In recent years, some advertisers tend to adopt auto-bidding tools to facilitate advertising performance optimization, making the classical \\emph{utility maximizer} model in auction theory not fit well. Some recent studies proposed a new model, called \\emph{value maximizer}, for auto-bidding advertisers with return-on-investment (ROI) constraints. However, the model of either utility maximizer or value maximizer could only characterize partial advertisers in real-world advertising platforms.
