Appendix

Solving Frozen Lake Using Monte Carlo

Frozen Lake is another simple game found in the OpenAI framework. This is a classic game where you can do sampling and simulations for Monte Carlo reinforcement learning. We have already described and used the Frozen Lake environment in Chapter 05, Dynamic Programming. Here we shall quickly revise the basics of the game so that we can solve it using Monte Carlo methods in the upcoming activity.

We have a 4x4 grid of cells, which is the entire frozen lake. It contains 16 cells (a 4x4 grid). The cells are marked as S – Start, F – Frozen, H – Hole, and G – Goal. The player needs to move from the Start cell, S, to the Goal cell, along with the Frozen areas (F cells), without falling into Holes (H cells). The following figure visually presents the aforementioned information:

Here are some basic details of the game:

Dr. Alexandra Galina Petre

Dr. Alexandra Galina Petre is a machine learning and data science expert, currently leading and teaching various engineering modules in Coventry, United Kingdom. Her leadership and management experience is linked to her work in quality management for the Airbus A380 and her IET membership. She received her Ph.D. in user feedback-based reinforcement learning for vehicle comfort control with a focus on revolutionary heating ventilation and air conditioning SARSA-based control systems that can learn from the drivers preferential changes to the UI. Her research is focusing on how thermal comfort depends on the occupants inclination to manual control as outlined in the SAE paper published in 2019, and the development of a novel Java-based user model (UBL) integrated within a car cabin environment. She is working on deep RL implementations in Python and R-based statistical developments within various automation and control projects.
