Options

Implementation of SMDP Q-Learning Options framework.

The enviroment is similar to the one specified in the original paper.

Requirements : pygame,gym,numpy,argparse

Usage:

python2 run.py run.py [-h] [--alpha ALPHA] [--epsilon EPSILON] [--gamma GAMMA]
          [--episodes EPISODES] [--verbose] [--goal GOAL] [--render]
          [--show-policy] [--algo ALGO] [--fo]

ALPHA : learning rate [Default:0.001]
EPSILON : Epsilon value for epsilon-greedy exploration [Default:0.2]
GAMMA : Discount [Default:0.9]
--render : to render the game for last 10% of the episodes
--show-policy : to show policy at the end
--verbose : to print steps and rewards 
ALGO : O/IO (Options/Intra-options) [Default:O]
GOAL : G1/G2 (goal-1/goal-2) [Default:G1]
--fo : learn fresh options #not recommended

Example :To run a game with default settings on goal-1 and show learnt policy at the end

python run.py --verbose --show-policy

Reference : Between MDPs and semi-MDPs: A framework for temporal abstraction in reinforcement learning

P.S : rewards have been scaled to 10
