The correlation time tau of the Swendsen-Wang and Wolff cluster algorithms is calculated at the critical point. The dynamic critical exponent z of both algorithms is also measured by using the numerical data for several lattice sizes up to L = 512. It is found for both algorithms that the autocorrelation time decreases considerably and the critical slowing -down effect reduces upon the introduction of bond disorder. Additionally, simulations with the Metropolis algorithm are performed, and the critical slowingdown effect is observed to be more pronounced in the presence of disorder, confirming the previous findings in the literature. Moreover, the existence of the non -self -averaging property of the model is demonstrated by calculating the scaled form of the standard deviation of autocorrelation times. Finally, the critical exponent ratio of the magnetic susceptibility is estimated by using the average cluster size of the Wolff algorithm.eninfo:eu-repo/semantics/closedAccessCritical-BehaviorAutocorrelationsExponentsPhaseHeatArticle10.1103/PhysRevE.109.0241402-s2.0-85186324275238491603Q1109WOS:001195456800007N/A
