Query: A numerical study of the Regge Calculus and Smooth Lattice methods on a
  Kasner cosmology   Two lattice based methods for numerical relativity, the Regge Calculus and
the Smooth Lattice Relativity, will be compared with respect to accuracy and
computational speed in a full 3+1 evolution of initial data representing a
standard Kasner cosmology. It will be shown that both methods provide
convergent approximations to the exact Kasner cosmology. It will also be shown
that the Regge Calculus is of the order of 110 times slower than the Smooth
Lattice method.
