“…Many numerical schemes have been proposed for solving these models, especially recently, high order schemes are very attractive due to their high resolutions for such problems with rich solution structures. For example, deterministic methods, there are finite difference, finite volume and finite element Eulerian methods [10, 12, 18-20, 43, 51, 53, 54,56,59], semi-Lagrangian methods [4,5,7,8,13,14,23,[31][32][33][34][35]38,45,46,52,58], and discontinuous Galerkin finite element methods [3,6,11,15,22,24,29,55,60], also see many other references therein. However, due to the highly oscillatory structure of such problems, linear type schemes for these problems would show significant spurious numerical oscillations, which might get worse with increased orders.…”
