Markov Game Learning Convergence Experiment

Description

The purpose of this project was to test the convergence of four different types of learning algorithms in a simple zero sum markov game (4x2 grid soccer game with 2 players). Each algorithm simulates 1,000,000 turns and checks if the Q-value of a particular state converges. The algorithms tested are: Q-Learning, Friend Q-Learning, Foe Q-Learning, and Correlated Q-Learning. Foe-Q and Correlated-Q use linear programming.

How To Run

1. Install Python 3.5

2. Please install cvxopt and the required dependencies http://cvxopt.org/install/

3. Using Python 3.5, run main.py. Some logging is printed to standard out to give me idea how far along each test is.

4. Results for each type of learning are printed to files q-learning.csv, friend-q.csv, foe-q.csv, ce-q.csv. Results are a csv with the following format: time-step,q-value-diff,pre-q-value,post-q-value,action/joint-action probabilities (foe-q & ce-q)
