Contents

The project contains 3 folders and 6 files.

1. data (folder): All datasets are in this folder.
2. comm (folder): This folder is used for community discovery.
3. result (folder): This folder is used to store the results and contains four examples of synthetic graphs.
4. main.py (file): The file is used to obtain the results of PrivGraph for End-to-End experiments.
5. main_vary_N.py (file): The file is used to obtain the results for different number of nodes.
6. main_vary_eps.py (file): The file is used to obtain the results for different privacy budget allocations.
7. main_vary_t.py (file): The file is used to obtain the results for different resolution parameters.
8. IM_spread.py (file): The file is used to obtain the results of influence maximization.
9. utils.py (file): The file includes some functions that are needed for other files.
