Thank you for your constructive feedback. We address the reviewers' main points below; however, we will also The motivation is unclear (R3, R4), in particular, as differentiable programming is not new (R4). The problem of searching in spaces of program architectures is also well-studied in classical program synthesis. Our paper's new observation, as noted by Prior efforts in machine learning research have used these datasets -- see "Generating Multi-Agent We will add further clarifying details about the DSL in the final version.
