This repository contains the reference implementation code for the paper "MGNN: Graph Neural Networks Inspired by the Distance Geometry Problem" (KDD 2023).

Note: Our experiments were conducted on a server equipped with a TITAN V GPU and a Quadro RTX 8000 GPU, with CUDA version 10.3. The hyperparameters used in our experiments may depend on the specific machine configuration and could vary with different versions of PyTorch due to the random number generator. You may need to adjust these parameters when running the code on different machines.

• matplotlib==3.5.1
• networkx==2.8
• numpy==1.21.4
• ogb==1.3.6
• torch==1.8.1+cu101
• torch_geometric==2.1.0.post1
• torch_scatter==2.0.7

cd src 

or

cd src-graphregression

for graph regression experiments. Then type:

python main.py (arguments)

To run our experiments, please follow the steps below.

• Install requirements.

pip install -r requirements.txt

• Run the 'Arranging Nodes with the Given Metric Matrices' experiment.

python synthetic.py

Then the output figures are generated in the 'out' folder.

• Run the 'Supervised Node Classification' experiment.

cd src
chmod +x *.sh

Then run the shell script of any specific model.

• Run the 'Graph Regression' experiment.

cd src-graphregression
chmod +x ZINC.sh
./ZINC.sh

The code of the pGNN model is borrowed from the official implementation.
