Abstract: We describe exponential time differencing algorithms (ETD) for nonlinear
parabolic partial differential equations of advection-diffusion-reaction type. These
are recently developed for the purpose of efficient computation through avoidance of
Newton iteration at each time step. In the algorithm development, operator splitting
ideas are introduced, which is an additional advantage of ETD schemes.
We discuss several test problems indicating solid performance of the algorithm, and
we finish with various applications from areas such as bio-mathematics, ocean wave
simulation and nonlinear optics( Nonlinear Schroedinger Equation ), and financial engi-
