SUMMARY

The discussion centers on the Wolff algorithm applied in Monte Carlo simulations for the 2D/3D Ising and classical 3D Heisenberg models. A key recommendation is to set the decorrelation steps to 10 times the lattice size (10*L) to ensure independent measurements of observables, particularly near critical temperatures. This guideline is established as a rule of thumb for effective simulation practices.

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 ?
