WitrynaCurrently, I did a Monte Carlo simulation with the local update and Wolff cluster updated in 2D classical Ising model. I use the autocorrelation function to compare 2 different algorithm in critical temperature (T ~ 2.269). That's what I got. Is it correct? The local updated algorithm didn't show the exponential decay in the beginning.
