| Research Type | Theoretical | As a proof of concept, a theoretical study is presented on the connection between existence / lack of free lunch in the two fields, showcasing a few ideas for improving computational complexity of certain supervised learning approaches. We structure the presentation in 3 incremental steps with respect to metric-evaluation costs: in Section 3.1 we describe the small-scale case of only one or two M -evaluations in total at most one of which is remaining in the budget; in Section 3.2 we progress to histories of arbitrarily-many already-evaluated interactions, but still at most one remaining to be evaluated; finally, in Section 3.3 we discuss the most general case of arbitrarily-large spent budgets and arbitrarily-large remaining budgets. In each section we first review the co-optimization perspective and results pertaining to free lunch and optimality, then derive and contrast their counterparts for supervised learning. We focus specifically on binary classification, but many of the ideas presented would apply in a multi-class situation. Throughout, we differentiate between the nature of free lunches for output mechanisms versus exploration mechanisms. We keep the presentation as informal as possible and support it with small but concrete examples; precise mathematical definitions of all concepts involved and proofs of the results can be found in the accompanying Online Appendix A. |

| Pseudocode | No | The paper describes algorithms conceptually and presents mathematical derivations and examples, but it does not contain any structured pseudocode or algorithm blocks. |
| Open Source Code | No | The paper does not contain any explicit statements about releasing source code, nor does it provide links to a code repository for the methodology described. |
| Open Datasets | No | The paper discusses problem examples such as 'Photo Labeling' and 'Protein Structure' to illustrate concepts, and uses abstract 'data D' in its theoretical examples and mathematical derivations. However, it does not use or provide access information for any publicly available or open datasets for empirical evaluation. |
| Dataset Splits | No | Since the paper focuses on theoretical derivations and uses abstract data examples (like 'data D' in section 3.1.2) rather than empirical datasets, it does not provide specific dataset split information. |
| Hardware Specification | No | The paper is a theoretical study and does not describe any experimental setup that would require specific hardware. Therefore, no hardware specifications are mentioned. |
| Software Dependencies | No | The paper is theoretical and focuses on mathematical derivations and conceptual discussions rather than implemented experiments. Consequently, it does not list any specific software dependencies with version numbers. |
| Experiment Setup | No | The paper presents a theoretical study with mathematical derivations and conceptual examples. It does not include an experimental section or details on hyperparameters, training configurations, or system-level settings. |
