Weekly plans and update for weeks 7 and 8

Hi all, during the last weeks we have discussed minimization methods, with an emphasis on gradient descent methods. These methods are discussed at for example http://compphysics.github.io/ComputationalPhysics2/doc/pub/cg/html/cg-reveal.html

These methods are interesting for our project in connection with the search for the optimal variational parameters. Finding the optimal parameters if often done with less Monte Carlo cycles. With the optimal variational parameters, we can then launch a large scale VMC calculation. Next week we will conclude this part. Thereafter we start with statistical estimations using methods like Bootstrapping, Jackknife and Blocking. These will be discussed during the intensive week March 2-6 and during the lecture on Thursday Feb 27.  The lectures on Gradient descent methods will be revised and partly rewritten till Thursday Feb 27.
