nonequilibrium phase transition into an absorbing state. The model is in a critical state when
the activation probability is adjusted at some precise value pc. Criticality is lost as soon as
the probability to activate sites at the first attempt, p 1, is changed. We show here that
criticality can be restored by “compensating” the change in p 1 by an appropriate change of
the second time activation probability p 2 in the opposite direction. At compensation, we …
