[ascl:1304.005] VOBOZ/ZOBOV: Halo-finding and Void-finding algorithms
Neyrinck, Mark; Hamilton, Andrew J. S.; Gnedin, Nickolay Y.
VOBOZ (VOronoi BOund Zones) is an algorithm to find haloes in an N-body dark matter simulation which has little dependence on free parameters.

ZOBOV (ZOnes Bordering On Voidness) is an algorithm that finds density depressions in a set of points without any free parameters or assumptions about shape. It uses the Voronoi tessellation to estimate densities to find both voids and subvoids. It also measures probabilities that each void or subvoid arises from Poisson fluctuations.
