Abstract
We study relaxation processes in spin systems near criticality after a quench from a high-temperature initial state. Special attention is pa id to the stage where universal behavior, with increasing order parame ter m(t)-t(theta), emerges from an early nonuniversal period. We compa re various algorithms, lattice types, and updating schemes and find in each case the same universal behavior at macroscopic times, despite s urprising differences during the early nonuniversal stages.
