Discretization algorithms serve as a critical pre-processing step within data mining and machine learning, transforming continuous attributes into discrete categories to enhance the interpretability ...
The IMEX schemes apply the implicit temporal method to only a small portion of the domain and use explicit calculations elsewhere, based on a convenient splitting algorithm. IMEX methods effectively ...
SIAM Journal on Numerical Analysis, Vol. 54, No. 5 (2016), pp. 2750-2774 (25 pages) We consider robust iterative methods for discontinuous Galerkin (DG) H(div, Ω)-conforming discretizations of the ...
A full multigrid method and fourth-order compact difference scheme is designed to solve the 3D Helmholtz equation on unequal mesh size. Three dimensional restriction and prolongation operators of the ...
