The armijo rule is really slow
The statistical update of sigmas is good
We need to stay sometime in low sigmas otherwise we do not optimize
the trace
Next setp is BFGS method

seems to run although it needs to be cross tested with a swiss roll example to
...
verify it. We are a little bit worried that the nearest neighbors might be wrong
and we have to check on that, because the optimum solution is 9% off the deasible
set. Need also to inser the constraint that the data are centered around zero.
