Abstract
In the recent study of the Ising model on a small world network by Pȩkalski [Phys. Rev. E 64, 057104 (2001)], a surprisingly small value of the critical exponent has been obtained for the temperature dependence of the magnetization. We perform extensive Monte Carlo simulations of the same model and conclude, via the standard finite-size scaling of various quantities, that the phase transition in the model is of the mean-field nature, in contrast to the work by Pȩkalski, but in accordance with other existing studies.
