Notice: The reproducibility variables underlying each score are classified using an automated LLM-based pipeline, validated against a manually labeled dataset. LLM-based classification introduces uncertainty and potential bias; scores should be interpreted as estimates. Full accuracy metrics and methodology are described in Coakley et alK. L. Coakley, T. Snelleman, H. Hoos, and O. E. Gundersen, "The embrace of open science: An analysis of a decade of AI research and 56 800 conference papers," Under Review, 2026..

Research Type Experimental In this section, we empirically evaluate the welfare performance and running time trade-offs of different mechanisms on a publicly available coverage problem. Our instances are constructed using a bipartite graph from SNAP (https://snap.stanford.edu/ data/wiki-Vote.html). ... We generate 10000 random instances per (n, s). ... Figure 1 shows the running time comparison of different methods and Figure 2 compares the welfare outcomes.

Open Source Code No The paper does not provide an explicit statement about releasing source code for the methodology or a link to a code repository.
Open Datasets Yes Our instances are constructed using a bipartite graph from SNAP (https://snap.stanford.edu/ data/wiki-Vote.html).
Dataset Splits No The paper describes generating '10000 random instances per (n, s)' by randomly sampling subsets and scaling costs. It does not provide specific training/test/validation splits for a machine learning model, as the evaluation is on different mechanisms over generated instances.
Hardware Specification No The paper does not mention specific hardware details (e.g., GPU/CPU models, memory) used for running the experiments or computations.
Software Dependencies No The paper mentions solving the optimization problem using a 'mixed integer program (MIP)' but does not specify the solver or its version number.
Experiment Setup Yes To create instances with varying sizes and value-to-cost ratios, for each pair (n, s), we randomly sample subsets of the sets of size n and scale their costs using Îș U[s, s2]. We generate 10000 random instances per (n, s).
