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..

| Pseudocode | Yes | Algorithm 1: CGCR(A): CG for Color Refinement; Algorithm 2: COLORS(M); Algorithm 3: CHARACTMAT(M); Algorithm 4: CGCR(A): CG for Color Refinement; Algorithm 5: HCGCR(A): Hashed CGCR; Algorithm 6: PICGCR(A): Power Iterated CGCR |
| Open Source Code | Yes | we implemented naive versions of CGCR, HCGCR (denoted as Hashing and available at https://github.com/rmgarnett/fast_wl/) and PICGCR in Matlab |
| Open Datasets | Yes | Table 1: Scaling results on graphs generated from http://www.cise.ufl.edu/research/sparse/matrices/index.html (matrices were turned into graphs using A := A + AT and thresholding |A| > 0). |
| Dataset Splits | No | The paper does not specify validation splits or detailed train/validation/test partitioning for the datasets used in experiments. |
| Hardware Specification | Yes | on a single Linux machine( 4 3.4 GHz cores, 32 GB main memory) |
| Software Dependencies | No | we implemented naive versions of CGCR, HCGCR (...) and PICGCR in Matlab. Matlab version number is not specified. |
| Experiment Setup | Yes | The convergence threshold ϵ for PI was set to 10 8 and the damping factor α to 0.95. The maximum number of PI iterations was set to 500 (denoted as PIfix) resp. to min(2k, τ) (PIflex). |
