 Figure: The probability P(x) and the test function f(x) for various algorithms.
FLA=Fast Linear Algorithm
Me =Metropolis
P_{5}=P(x) with h=5


 Figure: comparison of the time of simulation for various algorithms
for the stacked triangular antiferromagnetic lattices.
The critical temperature is shown by the squares
 FLA=Fast Linear Algorithm
 DHB=Direct HeatBath
 DHB_{2}=Modified HeatBath
 Me=Metropolis
 Me_{d}=like Me but the first angle is constrained
to be around the old spin (0 < first angle < d).
