Decorrelation steps in Wolff algorithm
Hello all,

I am doing a monte Carlo simulation using Wolff algorithm for the 2D/3D Ising and classical 3D Heisenberg model, I have been told that the rule of thumb is to make your decorrelation steps = 10*L where L is the size of lattice, and this is would be sufficient enough to make independent measurements for observables even near the critical temperature

So what is recommendation really ?
