We investigate the influence of correlated initial conditions on the temporal evolution of a [Formula Presented]-dimensional critical directed percolation process. Generating initial states with correlations [Formula Presented] we observe that the density of active sites in Monte Carlo simulations evolves as [Formula Presented] The exponent κ depends continuously on σ, and varies in the range [Formula Presented] Our numerical results are confirmed by an exact field-theoretical renormalization group calculation.
