Reproducibility Variable Result LLM Response
Research Type Theoretical We answer this question affirmatively and present an algorithm that uses polynomial number (specifically, O(n5) queries). This solves the main open problem stated by Caragiannis and Rathi (2024). Our analysis uses a potential function argument that measures progress towards learning the underlying edge-weight information.

Pseudocode Yes Algorithm 1: An efficient algorithm to find welfare-optimal action sequence for OSM
Open Source Code No The paper does not provide any concrete statement about releasing code for the methodology described in this paper. It refers to another paper (Caragiannis and Rathi (2024)) for details on a truthful implementation paradigm, not source code for the current work.
Open Datasets No The paper does not use or refer to any specific publicly available datasets for experimental evaluation. It discusses a theoretical model involving a 'complete bipartite graph G = Kn,n' and 'agent-item preferences' that are learned through 'action sequence queries'.
Dataset Splits No The paper does not use any specific datasets, therefore, it does not provide any information regarding dataset splits.
Hardware Specification No The paper focuses on theoretical algorithm design and query complexity, and as such, does not provide any details about specific hardware used for experiments.
Software Dependencies No The paper is theoretical and describes an algorithm without presenting an empirical implementation. Therefore, it does not specify any software dependencies with version numbers.
Experiment Setup No The paper presents theoretical work on algorithm design and query complexity, rather than empirical experiments. As such, it does not describe any experimental setup details, hyperparameters, or training configurations.
