CVTP is a dataset directory which contains examples of CVTP's, that is, Centroidal Voronoi Tessellations defined on a periodic domain, usually a rectangle or hyperrectangle.
Each dataset contains N points in M-dimensions, with the points having the property that they are (approximately) the centroids of the Voronoi regions that they generate within one cell of a periodically repeating region.

TABLE, a file format which is used to store the data.
PLOT_POINTS, a FORTRAN90 program which was used to make images of some of the 2D datasets.
TABLE_TOP, a FORTRAN90 program which was used to make pairwise coordinate plots of some of the higher dimensional datasets
A typical (but small) dataset looks like this:
0.378753 0.919641 0.725977 0.572210 0.551973 0.246525 0.264802 0.248364 0.052727 0.745158 0.057432 0.457647 0.395623 0.587517 0.710814 0.904034 0.839889 0.240473 0.046507 0.033340
There is a family of datasets in M = 2 dimensions. At least for the lower values of N, it is useful to look at plots of this data.
There is a family of datasets in M = 7 dimensions.
There is a family of datasets in M = 16 dimensions.
You can go up one level to the DATASETS directory.
