By Hiroshi Shinaoka Using this model, I was able to calculate the expectation values of the absolute value of spin magnetization for L xL spins systems with L=4, 8, 16 and 32 as a function of temperature (the Ising model is the representation of spins on a graph). It then computes the neighbor agreement at each cell.
