Topic 3
-Explain the challenge with calculating free energies from molecular simulations. -Outline the thermodynamic perturbation approach. -Calculate the free energy difference of two states of a simple model system by thermodynamic perturbation. -Explain how you might evaluate the results of a free energy calculation.

Topic 4
-Give examples of reaction coordinates commonly used to study free energy changes in biophysical systems -Explain why the use of biased potential could offer a strategy for dealing with the timescale problem in MD. -Give a basic overview of the umbrella sampling and metadynamics methods. -Describe the pros and cons of umbrella sampling with each other and with other methods covered in this course -Be aware of how these techniques may be used to study biophysical systems.
