I don't know any code, but it should be too difficult by bgoing
through a KdTree.
> Worst case, it does not look too bad to code, but I am interested by any advice. I haven't done my reading yet, and I don't know how ill-posed a problem it is. I had in mind starting from a set of points and iterating the computation of the objective function's value at the barycenters of these points, and updating this list of points. This does raise a few questions on what are the best possible updates.
In this case, you may want to check Nelder-Mead algotihm (also known
as down-hill simplex or polytope), which is available in
scikits.optimization, but there are other implementations out there.
Cheers ;)
