Abstract :
A generic algorithm is presented that can be used, along with simulated annealing, to provide lattice vector quantizers based on different lattices. It is a two-stage algorithm, with each stage based on different ways of looking at the structural regularity of the lattice. The first stage is based on the mathematical definition of a lattice, while the second stage depends on the observation that the view of the surroundings at any lattice point is identical to that at any other lattice point
