Plans for the fifth week, Feb 17-21

Dear all, welcome back to FYS4411/9411. The plans this week are to discuss:

• Reminder on Fokker-Planck equation and Langevin equations (partly from last week)

• Programming elements of correlation function (needed later)

• Start optimization: Expressions for derivatives as functions of the variational parameters

• and if we get time, we start discussing Newton's method and gradient descent. Methods like Steepest descent and Conjugate Gradient Descent will be discussed next week.

The slides (jupyter-notebook) are at https://github.com/CompPhysics/ComputationalPhysics2/blob/gh-pages/doc/pub/week5/ipynb/week5.ipynbLinks to an external site.

Best wishes to you all,

Morten
