| Research Type | Experimental | We empirically demonstrate that graph neural PDEs are intrinsically more robust against topology perturbation as compared to other GNNs. ... We verify that the new model achieves comparable state-of-the-art performance on several benchmark datasets. 5 Experiments In this section, we compare graph neural PDEs under different flows to popular GNN architectures: |

| Pseudocode | No | The paper includes architectural diagrams (e.g., Fig. 2) but does not contain explicitly labeled pseudocode or algorithm blocks. |
| Open Source Code | Yes | Our experiment codes are provided in https://github.com/zknus/Robustness-of-Graph-Neural-Diffusion. |
| Open Datasets | Yes | In our experiments, we use the following datasets: Cora (citation networks) [44], Citeseer (citation networks) [48] and Pub Med (biomedical literature) [49]. We use a refined version of these datasets provided by [50]. |
| Dataset Splits | Yes | The remaining nodes are divided into a train set (60%) and val set (10%), for training and validation respectively. |
| Hardware Specification | Yes | Our experiments are run on a Ge Force RTX 3090 GPU. |
| Software Dependencies | No | The paper mentions using an implicit Adam PDE solver and implicitly refers to PyTorch by discussing GNNs, but it does not specify version numbers for any software dependencies. |
| Experiment Setup | Yes | The implicit Adam PDE solver with step size 2 is used for Beltrami. ... For GRAND/BLEND, we stack three neural PDE layers using the architecture proposed in Fig. 2... ...the maximum allowable injected nodes and the maximum allowable injected edges are set to 50 for Cora and Citeseer, and 300 for Pub Med. |
