Thirteen chemical measurements were carried out on each of 178 wines from three regions of Italy [53]. These data are available from the website for this book. Using one or more heuristic search methods from this chapter, partition the wines into three groups for which the total of the within-group sum of squares is minimal. Comment on your work and the results. This is a search problem of size 3p
where
p
= 178. If you have access to standard cluster analysis routines, check your results using a standard method like that of Hartigan and Wong [317].
