As we discussed, I'm a little worried here. For a "hill climbing" method to work, there has to be some notion of continuity. It's not a (useful) Monte Carlo method to just be guessing point solutions in a huge space in the hope of finding the right one. Please think carefully, for the problems that you propose, about what is the nature of the solution space, does up-hill stepping make sense, etc.

Interesting!

In slide 12, how do you actually evaluate the proposed functional exp(t d^2/dx^2) on a function? My guess is
that you do it in Fourier space, where it is just a Gaussian low-pass filter. Why is that optimal?

Then, in your slide 21, this would also correspond to the
integral method that convolves with a Gaussian.

In branch and bound (in this context) I'm not sure what
is the class of problems for which you can know how to compute the bounds.
