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..

Reproducibility Variable Result LLM Response
Research Type Experimental Empirically, SAM reduces measured sharpness and value-prediction error and improves returns across Humanoid Bench, Atari-100k, and high-Do F Deep Mind Control tasks. Augmenting existing MBRL algorithms with SAM increases mean return, with especially large gains in settings with high dimensional state action spaces.

Pseudocode No The paper describes algorithms and mathematical formulations but does not contain a clearly labeled 'Pseudocode' or 'Algorithm' block.
Open Source Code Yes 1Code: https://github.com/autonlab/MBRL-flat-minima.git
Open Datasets Yes Empirically, SAM reduces measured sharpness and value-prediction error and improves returns across Humanoid Bench, Atari-100k, and high-Do F Deep Mind Control tasks.
Dataset Splits No The paper discusses training durations like '2M environment steps' and '100k environment steps' and 'running four random seeds' which are common in RL benchmarks, but it does not specify explicit training/validation/test dataset splits in terms of percentages, sample counts, or specific predefined files for static datasets.
Hardware Specification No We would like to thank Pittsburgh Supercomputer Center for providing access to their HPC resources. However, the specific types (e.g., GPU models, CPU types) of these resources are not detailed.
Software Dependencies No The paper mentions using existing algorithms and frameworks (e.g., TD-MPC2, TWISTER) and implicitly relies on standard ML libraries, but it does not provide specific version numbers for any software dependencies like Python, PyTorch, or other libraries.
Experiment Setup Yes Baseline hyper-parameters follow the original papers; SAM introduces a single radius parameter ρ App. Tab. 4. Unless otherwise noted, all hyper-parameters follow the TD-MPC2 defaults, and the SAM radius ρ is selected via a small coarse grid in App. Tab. 5.
