Generalized Population-Based Training With Pairwise Learning (GPBT-PL) arXiv

Code for the Generalized Population-Based Training With Pairwise Learning (GPBT-PL) algorithm, from the paper Generalized Population-Based Training for Hyperparameter Optimization in Reinforcement Learning.

The GPBT framework is implemented based on ray. Heavily inspired by ray tune PBT example, GPBT-PL is included in the ray.tune library, which is the official supported implementation.

Running the code

To run the PPO experiment, use command:

python run_ppo.py 

To run the IMPALA experiment, use command:

python run_impala.py
