The efficient numerical methods for solving the American option pricing model under jump-diffusion is studied. First of all
the high accuracy compact difference scheme is applied to discrete the option pricing model in the spatial direction
and discrete the temporal variable of the resulting ordinary differential equation to the linear complementarity problem (LCP). The approximation value of option price is obtained by solving the LCP. Finally
in order to overcome the nonsmoothness of payoff function
the singularity separating method is utilized for the American option pricing model to improve the accuracy of calculation. Numerical examples demonstrate the superiority of the algorithm.
