Simulasi Numerik dari Model Dinamika Opini dengan Gangguan pada Kisi Dua Dimensi

Abstract

This study examines the Sznajd opinion dynamics model with a noise parameter has been analyzed. The Sznajd model describes agent-agent interaction rules to reach an agreement or consensus. The model is implemented on a two dimensional (2D) square lattice network, which the four nearest agents in the population are randomly selected. In a two-dimensional square lattice, neighboring agents are agents in the square formation (Si,j, Si+l,j, Si+l,j+l, Si,j+1). This study also uses numerical calculations with the mean-field approach using the Monte Carlo method for some macroscopic parameters of the system such as order parameters m, susceptibility y , and Binder cumulant U. The two-dimensional square lattice system studied has N=LxL with sizes L=8,16,32,dan 64. In this study also obtained the critical exponent parameter values of the model wi0th the help of finite-size scaling, namely B=0.125, y=-1.71 and v=1.8 and the critical point value pc=0.0867 which shows that the model is in a different universality class with the Sznajd model on a two-dimensional square lattice with anticonformity.
