Adjusting the game difficulty by changing AI behaviors with Reinforcement Learning

The main purpose of this research is to adjust the game difficulty with Reinforcement Learning. We aim to adjust the AI behavior according to the player skill. The developed game looks like a 2D fighting game. The goal of the paper is to create an AI which learns from the player, but not in order to become stronger, but to adapt it behavior in order to give a good game experience to the player.
