We explore a quantitative description of Wolfram's classification of elementary cellular automata based on fractal dimensions. We find the· fractal dimension to be a global measure in classifying elementary cellular automata independent of initial conditions. On the other hand, the results of our analysis of rules in Class 3 numerically confirm the existence of a wide range of dynamics among rules in Class 3. The main reason for this is due to the fact that the rules with the Sierpinski structure in Class 3 have the capacity to behave like rules in Class 2 depending on their initial conditions. Furthermore, we apply mutual information to investigate how elementary cellular automata handle information throughout the iterations of time steps. We discover a similarity among Rule 30, Rule 110 and Rule 22, and give further supporting evidence for Wolfram's conjecture that Rule 30 and Rule 22 may be universal.
