Weekly plans and update for week 6

Hi all, we hope this week has evolved in the best possible way. Here's out weekly digest with plans for today's lecture and lab.
Last week we started discussing the practicalities on importance sampling. Our focus was on the elements we need to include in our program. Today we will wrap up our discussions by looking into the theory of Green's functions, the diffusion equation and the Fokker-Plank and Langevin equations. 
Towards the end of the lecture we start our discussion of gradient methods. This will be our next programming element and is needed in order to be able to find the optimal variational parameters before we launch a large VMC calculation. The slides are partly those from last week (Feb 1-5) and on gradient methods, the slides are at
for example http://compphysics.github.io/ComputationalPhysics2/doc/pub/week5/html/week5-reveal.html, or just scroll down the page http://compphysics.github.io/ComputationalPhysics2/doc/web/course and you will find the teaching material from last week and this week.

Best wishes,
Morten and ?yvind
