Generally, the problem of finding clusters that maximizes typical clustering objective functions that relate to graph density is known to be NP-hard (Jagota, 1995).
But a computer used to calculate star clusters would need to be much faster than a solar system machine (the solar system, after all, only has 10 bodies, not a million, and at 4.5 billion years old is less than half the age of the typical cluster).
In addition, typical clusters of similar research approaches were identified.
LEACH [8] is a typical clustering routing algorithm for WSNs.
Inset shows higher magnification of a typical cluster.
By comparison, typical clusters of galaxies can be nearly 10 million light-years across.
COSMOS is a scalable single-image file system designed for Dawning2000 superserver, a typical cluster system.
Low Energy Adaptive Clustering Hierarchy (LEACH) is a typical cluster-based protocol using a distributed clustering formation algorithm [5].
However, symptomatic cases of otherwise typical cluster headache have been reported.
Cells A, B, and C denote the three cells of a typical cluster.
LEACH is a typical cluster routing protocol and is introduced to CWSN.
