Abstract: We analyze the evolution of Sznajd Model with synchronous updating in several complex networks. Similar to the model on square lattice, we have found a transition between the state with nonconsensus and the state with complete consensus in several complex networks. Furthermore, by adjusting the network parameters, we find that a large clustering coefficient does not favor development of a consensus. In particular, in the limit of large system size with the initial concentrationp =0.5of opinion +1, a consensus seems to be never reached for the Watts–Strogatz small-world network, when we fix the connectivitykand the rewiring probabilityps; nor for the scale-free network, when we fix the minimum node degreemand the triad formation step probabilitypt.
