Multi Type Mean Field Reinforcement Learning

Implementation of MTMFQ in the paper Multi Type Mean Field Reinforcement Learning.

The environments contain 4 teams training and fighting against each other. Multi Battle Game environment has four teams with 72 agents each.

Code structure

• See folder Multibattle for training and testing environments of the Multi battle environment.

• See folder Multigather for training and testing environments of the Multi gather environment.

• See folder Predatorprey for training and testing environments of the Predaotor Prey environment.

In each of these three game directories, the files most relevant to our research are:

• /mfrl/examples/battle_model/python/magent/builtin/config/battle.py: Script that defines the rewards for the different games and is game-dependent.

• /mfrl/examples/battle_model/senario_battle.py: Script to run the training and testing, which other scripts call into, and is game-dependent.

• /mfrl/train_battle.py: Script to begin training the game for 2000 iterations and almost identical across games. The algorithm can be specified as a parameter (MFAC, MFQ, IL, or MTMFQ).

• /mfrl/battle.py: Script to run comparative testing (creating 4 types of agents, where each type is one of the 4 algorithms) and is almost identical across games.

• /mfrl/examples/battle_model/algo: This directory contains the learning algorithms, and is identical across all three games.

Clone the repository

git clone https://github.com/BorealisAI/mtmfrl

Build the MAgent framework

cd mtmfq/multibattle/mfrl/examples/battle_model
./build.sh

Similarly change directory and build for multigather and predatorprey folders for those testbeds.

Training and Testing

cd mtmfq/multibattle/mfrl
export PYTHONPATH=./examples/battle_model/python:${PYTHONPATH}
python3 train_battle.py --algo mtmfq

Run file battle.py for running the test battles.

For more help, look at the instrctions in MAgent and MFRL
