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 No The paper describes the methodology with mathematical formulations and high-level steps, but does not present any formal pseudocode or algorithm blocks.
Open Source Code Yes The NeurIPS Paper Checklist states for 'Open access to data and code': 'Answer: [Yes] Justification: See supplementary material.'
Open Datasets Yes In this paper, we comprehensively evaluate the visual reasoning capabilities of our method by leveraging six existing datasets, enhanced through subtask categorization, error-prone data filtering, and dataset restructuring. Specifically, we define three task categories as follows. Visual Counting... Specifically, we filtered and corrected 35K samples from CLEVR-Math [1]... To assess generalization under domain-shift (DS), we constructed 1K new samples using 3D assets from Super-CLEVR [51]... Structure Perception... We filtered 4.5K training samples and 820 ID test samples from Geo170K [52] and Math360K [55], along with 800 samples from Geometry3K [85]... Spatial Transformation... We generated 100K samples using TRANCE [56]...
Dataset Splits Yes Visual Counting... filtered and corrected 35K samples from CLEVR-Math [1] for training and 1K test samples for in-domain (ID) evaluation... Structure Perception... filtered 4.5K training samples and 820 ID test samples from Geo170K [52] and Math360K [55], along with 800 samples from Geometry3K [85]... Spatial Transformation... selected 60K for training and 6K for testing...
Hardware Specification Yes All experiments were conducted on a cluster of servers, each equipped with 8 A800 GPUs.
Software Dependencies No Our implementation is built on the open-source frameworks Open-R1 [88] and vLLM [89], ensuring reproducibility and scalability. The paper mentions frameworks used but does not provide specific version numbers for any key software components.
Experiment Setup Yes Table 4: Detailed configuration for each training stage of Reason-RFT. The table presents the training parameters for the 2B model and 7B model across three visual reasoning tasks... includes: Per-device Batch Size, Gradient Accumulation, LR, Epoch, Optimizer, Deepspeed, Weight Decay, Warmup Ratio, LR Schedule, Max Seq. Length, Max Compl. Length, Num. of Compl., GPU Nums. And: For the Visual Counting task and Spatial Transformation task, we trained the models for 1 epoch each... For the Structure Perception task... we extended the training duration to 5 epochs... In the Reason-RFT training pipeline, all models underwent an initial Co T activation stage with 1,600 samples before proceeding to the RL phase.
