We investigate the influence of correlated initial conditions on the temporal evolution of a (d+1)-dimensional critical directed percolation process. Generating initial states with correlations (siSi+r) to approximately rσ-d we observe that the density of active sites in Monte Carlo simulations evolves as ρ(t) to approximately tκ. The exponent κ depends continuously on σ and varies in the range -β/ν≤κ≤η. Our numerical results agree with that of an exact field-theoretical renormalization group calculation.
