Abstract
We present a numerical determination of the scaling functions of the
magnetization, the susceptibility, and the Binder's cumulant for two
nonequilibrium model systems with varying range of interactions. We
consider Monte Carlo simulations of the block voter model (BVM) on
square lattices and of the majority-vote model (MVM) on random graphs.
In both cases, the satisfactory data collapse obtained for several
system sizes and interaction ranges supports the hypothesis that these
functions are universal. Our analysis yields an accurate estimation of
the long-range exponents, which govern the decay of the critical
amplitudes with the range of interaction, and is consistent with the
assumption that the static exponents are Ising-like for the BVM and
classical for the MVM.
