We introduce new fast canonical local
algorithms for discrete and continuous spin systems.
We show that for a broad selection of spin systems
they compare favorably to the known ones except for
the Ising ±1 spins.
The new procedures use discretization scheme and the
necessary information have to be stored
in computer memory before the simulation.
The models for testing discrete spins are the
Ising ±1, the general Ising S or Blume-Capel model,
the Potts and the clock models.
The continuous spins we examine are the O(N) models, including
the continuous Ising model (N=1), the Ising model (N=1),
the XY model (N=2), the Heisenberg model (N=3), the
Heisenberg model (N=3), the O(4) model with applications
to the SU(2) lattice gauge theory, and the general O(N) vector spins
with
