ppo_gi.py

PPO graph isomorphism experiment using a grid of hyperparameters.

This script runs through a grid of hyperparameters, specified in the param_grid dict. If the MULTIPROCESS variable is set to True, the experiments are run using a pool of workers (specified by the --num-workers command line argument). Otherwise, the experiments are run sequentially.

Additional settings, like whether to log to W&B can be set via command line arguments. Run the script with the --help flag to see all available arguments.

scripts/ppo_gi.py

Run hyperparameter experiments in parallel
