Reproducibility Variable Result LLM Response
Research Type Experimental In this section we apply Algorithm 1 to provide experimental results on synthetic data and two real-world data: APA election data (large N, small tmax), and University’s homepage search (small N, large tmax).

Pseudocode Yes Algorithm 1 t selection algorithm
Open Source Code No The paper does not provide any explicit statements or links indicating that the source code for the described methodology is publicly available.
Open Datasets Yes We consider the problem of ranking with a small number of items and large sample size. The data consists of N = 15449 rankings over tmax = 5 candidates during the American Psychological Association’s presidential election in 1980. ... See (Coombs et al., 1984; Diaconis, 1989) for further background.
Dataset Splits No The paper does not specify dataset splits (e.g., percentages or counts for training, validation, and testing sets).
Hardware Specification No The paper does not provide any specific details about the hardware used to run the experiments (e.g., CPU, GPU models, memory).
Software Dependencies No The paper does not provide specific version numbers for any software dependencies or libraries used in the experiments.
Experiment Setup Yes We generate 50 sets of N = 1000 rankings from the IGM model (1.3) with θ = (1, 0.9, 0.8, 0.7, 0.6, 0.5, 0, . . .) and π0 = id. We restrict all observed rankings to the first tmax = 6 components.
