We introduce a new type of diagram called the VV(c)-diagram (the visibility–Voronoi diagram for clearance c), which is a hybrid between the visibility graph and the Voronoi diag...

In this paper, we show that there exists a (k, ε)-coreset for k-median and k-means clustering of n points in IRd , which is of size independent of n. In particular, we construct ...
