High-order WENO-based semi-implicit Newton-type fast sweeping methods for static Hamilton-Jacobi equations
Yuan Liu, Jianliang Qian
In this paper, we propose high-order weighted essentially non-oscillatory (WENO)-based semi-implicit Newton-type Gauss-Seidel Lax-Friedrichs fast sweeping methods for solving the g…
