ECAI 2023 - Graph Neural Networks For Mapping Variables Between Programs

This repository contains the code and data used for the paper "Graph Neural Networks For Mapping Variables Between Programs", accepted at ECAI 2023.

We present a novel graph program representation that is agnostic to the names of the variables and for each variable in the program contains a representative variable node that is connected to all the variable's occurrences. Furthermore, we use GNNs for mapping variables between programs based on our program representation, ignoring the variables' identifiers; We represent each program as a graph using the script gen_progs_repr.py, as explained in [1, 2].

To understand the entire pipeline, from the dataset generation to the repair process, the interested reader is refered to our main script 'run_all.sh'.

The generation of the datasets (training, validation and evaluation) and the training of our GNN has been commented since it takes a few hours to compute. Only the mapping computations and the program repair tasks were left uncommented. In this repo only the evaluation dataset is available.

  • How to execute:
chmod +x run_all.sh
bash run_all.sh

Installation Requirements

The following script creates a new conda environment named 'gnn_env' and installs all the required dependencies in it.

chmod +x config_gnn.sh
bash config_gnn.sh

Introductory Programming Assignments (IPAs) Dataset

To generate our evaluation set of C programs we used MultIPAs [3], which is a program transformation framework, to augment our dataset of IPAs, C-Pack-IPAs [4].
