Abstract: Embodiments of the present disclosure describe methods for efficient wavefield solutions, the methods including defining a wave equation as a linear portion and as a nonlinear portion; and solving the wave equation via an iterative process, the iterative process including, at each iteration, performing LU decomposition before solving the nonlinear portion, or obtaining best finite difference coefficients by solving an optimization equation.
