Reproducibility Variable Result LLM Response
Research Type Experimental Using our problems in experiments, we provide some insights into the nature of several statistical models of elections.In this section we use the MAX. COMMON VOTER-SUBELECTION problem to analyze similarity between elections generated from various statistical models.

Pseudocode No The paper states that a formal ILP formulation is available in the full version, but it does not include pseudocode or a clearly labeled algorithm block in the main text.
Open Source Code Yes The source code used for the experiments is available in a Git Hub repository1. 1https://github.com/Project-PRAGMA/Subelections-AAAI2022
Open Datasets No The paper describes generating its own datasets using various statistical models ('For each scenario and each two of the above-described models, we have generated 1000 pairs of elections'), but it does not provide concrete access information (link, DOI, repository, or citation) for these generated datasets to be publicly available.
Dataset Splits No The paper describes generating elections and analyzing their similarity, but it does not specify training, validation, or test dataset splits, as the experiments do not involve model training.
Hardware Specification Yes We ran CPLEX on a single thread (Intel(R) Xeon(R) Platinum 8280 CPU @ 2.70GH) of a 448 thread machine with 6TB of RAM.
Software Dependencies No The paper mentions using 'the CPLEX ILP solver' but does not specify its version number, nor does it list any other software components with version numbers.
Experiment Setup Yes We consider elections with 4, 7, or 10 candidates and with 50 voters. For each scenario and each two of the above-described models, we have generated 1000 pairs of elections (for urn elections, we used α {0.1, 0.5} and for the Mallows model, we used norm-φ {1/3, 2/3}).
