Graeme,
just by the way, do you happen to know this one?

Recently I stumbled over this paper, and what initially came into my
mind was that this algorithm seems to be taylored for problems like
dispcal, i.e. for minimizing a non-deterministic, expensive objective
function. It seems to be a bit complex and therefore expensive to
implement though [there is however a Matlab implementation available
freely for download, but I did not yet find some time to evaluate it].
Kind Regards,
Gerhard
