Review for NeurIPS paper: Improving Policy-Constrained Kidney Exchange via Pre-Screening

Neural Information Processing Systems 

Weaknesses: I have the following concerns about the paper: 1. This paper introduces an algorithm to find a suboptimal query strategy, and it does not provide an algorithm to find the optimal matching. For finding the best query strategy, we need to know the optimal matching policy as a function of the query edges. This paper assumes that after selecting a specific query, the optimal matching and the maximum utility are available to the decision-maker. More precisely, this paper assumes that V S(q) is available to the decision-maker.
