Abstract
We performed a numerical simulation of X-Y model on the two-dimensional random lattice using cluster update algorithm. The critical region was found around β ≈ 1.0 by the peaks in the specific heat and the susceptibility. The autocorrelation in energy and the square of magnetization was also calculated. The results show that the critical slowing down was greatly reduced.
