WENO methods

In numerical solution of differential equations, WENO (weighted essentially non-oscillatory) methods are classes of high-resolution schemes. WENO are used in the numerical solution of hyperbolic partial differential equations. These methods were developed from ENO methods (essentially non-oscillatory). The first WENO scheme is developed by Liu, Chan and Osher in 1994.[1] In 1996, Guang-Sh and Chi-Wang Shu developed new WENO scheme[2] which is called WENO-JS.[3] Nowadays, there are many WENO methods.[4]
