We propose a hybrid heuristic procedure based on scatter search and tabu search for the problem of clustering objects to optimize multiple criteria. Our goal is to search for good approximations of ...

This example uses computer-generated data to mimic a Hertzsprung-Russell plot (Struve and Zebergs 1962, p. 259) of the temperature and luminosity of stars. The data are plotted and displayed in Output ...

If the population clusters are sufficiently well separated, almost any clustering method performs well, as demonstrated in the following example using single linkage. In this and subsequent examples, ...

We have started a large project to study the near-infrared luminosity-linewidth (Tully-Fisher) relation using H- and I-band surface photometry of spiral galaxies. A preliminary study of 20 spirals in ...
