Hi all, we hope you are doing well. Here comes the standard weekly update with our plans for this and next week.
Last week we attempted at a conclusion on gradient methods and for project 1, the simplest plain gradient descent does a pretty decent job.
What we have now is
1) a VMC program with brute force and importance sampling
2) hopefully added a gradient descent optimization in order to get the best variational parameter(s).

Now we need to think more carefully about statistical errors and we are going to encounter two much used techniques, the so-called bootstrap technique and the blocking method.
Hopefully these methods (to be discussed this week and next week) allow us to get a better estimate of the standard deviation and thus our statistical error.
The learning material is at for example http://compphysics.github.io/ComputationalPhysics2/doc/pub/week8/html/week8-reveal.html or as a jupyter-notebook at http://...
