Install miniconda3 from the official website and run the following script:

bash scripts/install.sh

We use games implemented by OpenSpiel [1] and PokerRL [2]. Run the following script to assess the performance of CFR variants on testing games. The results are saved in the folder results.

conda activate PDCFRPlus
python scripts/parallel_run.py --algo CFRPlus
python scripts/parallel_run.py --algo LinearCFR
python scripts/parallel_run.py --algo DCFR
python scripts/parallel_run.py --algo PCFRPlus --gamma=2
python scripts/parallel_run.py --algo PCFRPlus --gamma=5
python scripts/parallel_run.py --algo DCFRPlus --gamma=4 --alpha=1.5
python scripts/parallel_run.py --algo PDCFRPlus --gamma=5 --alpha=2.3
