(a) Chaotic sequence for EL map for initial conditions of , , and and in the same figure, two graphs are plotted for EL map for initial conditions of , , and and , , and . (b) Chaotic sequence for EL map for initial conditions of , , and and in the same figure, two graphs are plotted for EL map for initial conditions of , , and and , , and . It can be seen that initially up to 35 iterations, all the sequences of both graphs are same; however after that point, the sequences are completely out of phase to each other.
