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..

IJCAI 2019 | Venue PDF | LLM Run Details
| Reproducibility Variable | Result | LLM Response |
|---|---|---|
| Research Type | Experimental | Our experiments with GPS traces on a road network and user-navigation on Wikipedia con๏ฌrm that GRETEL can adapt to graphs with very different properties, while comparing favorably to previous solutions. |

| Pseudocode | No | The paper describes algorithmic steps and mathematical formulations for GRETEL's components and operations but does not present them in clearly labeled 'Pseudocode' or 'Algorithm' blocks. |
| Open Source Code | Yes | Information about the datasets and hyper-parameters are displayed in Table 1, code and datasets are publicly available at https://github.com/jbcdnr/gretel-path-extrapolation. |
| Open Datasets | Yes | Information about the datasets and hyper-parameters are displayed in Table 1, code and datasets are publicly available at https://github.com/jbcdnr/gretel-path-extrapolation. ... We ran an experiment based on a small dataset of food deliveries (229 traces) occurring over the Open Street Map road network of Lausanne (18156 nodes, 32468 edges). ... In the Wikispeedia game [West et al., 2009]... |
| Dataset Splits | No | Table 1 lists 'train/test 80% / 20%' for both GPS and Wikispeedia datasets, but no explicit validation split percentage or methodology is mentioned. |
| Hardware Specification | No | The paper does not provide any specific details about the hardware (e.g., GPU models, CPU types, memory) used to run the experiments. |
| Software Dependencies | No | The paper mentions training parameters like 'Adam learning rate' but does not specify software dependencies (e.g., Python, PyTorch, TensorFlow versions) with specific version numbers. |
| Experiment Setup | Yes | Information about the datasets and hyper-parameters are displayed in Table 1: Adam learning rate 0.01 0.1 batch size 5 10 # epochs 200 5. |
