Abstract: Space cells are divided by equal distance step for calculating mutual information, and delay time. This approach is simpler than that of equal probability method. Numerical results indicate that this method can determine the correct delay time, and yield the reconstructed states in the case of forced brusselator.

Key words: cells method, mutual information, delay time, attractor
