That is right. It is a part of materials engineering. Could say its a standard method in it. Better description is always on Wikipedia :)

And I thought R can do all instead of making coffee. 2012/10/4 Bert Gunter <gunter.ber...@gene.com> > I'm going to make a wild guess that this might have something to do > with "bump hunting" =local conditional extrema.
