Autocorrelation Function of Magnetization of 2D Ising Model
------------------------------------------------------------------------
Summary:

Sample source code of Monte Calro simulation for the two-dimensional
Ising model on the square lattice.
Autocorrelation functions of magnetization at the critical temperature
are calculated by three methods, Single-Flip, Swendsen-Wang, and
Wolff algorithm, respectively.
-----------------------------------------------------------------------
Usage:

$ make clean
$ make acf
