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 compare through simulations the performance of DS-PSRL algorithm with the latest PSRL algorithm called Thompson Sampling with dynamic episodes (TSDE) Ouyang et al. [2017b]. We experimented with the River Swim environment Strehl and Littman [2008], which was the domain used to show how TSDE outperforms all known existing algorithms in Ouyang et al. [2017b]. |

| Open Source Code | No | The paper does not provide an explicit statement or link to open-source code for the methodology described. |
| Open Datasets | Yes | We experimented with the River Swim environment Strehl and Littman [2008], which was the domain used to show how TSDE outperforms all known existing algorithms in Ouyang et al. [2017b]. |
| Dataset Splits | No | The paper mentions using the River Swim environment and various settings for experiments but does not explicitly specify training, validation, and test dataset splits or percentages. |
| Hardware Specification | No | The paper does not provide any specific hardware details such as GPU/CPU models or memory used for running the experiments. |
| Software Dependencies | No | The paper does not provide specific software names with version numbers that are required to reproduce the experiments. |
| Experiment Setup | Yes | The MDP consists of K states arranged in a chain with the agent starting in the leftmost state (s = 1). The reward function is given by: r(s, a) = 5 if s = 1, a = left; r(s, a) = 10000 if s = K, a = right; and r(s, a) = 0 otherwise. We assumed the true model of the world was = 2 and that the agent starts in the left-most state. The initial parameters of the priors were set to one (uniform) for the non-zero transition probabilities of the River Swim problem and zero otherwise. In our experiment we set n = 2 and d = 2. |
