Classical numerical schemes require a small time step to compute accurately the solution since it is necessary to capture rapid time scales. In this chapter, we consider a 1D advection-diffusion eq

The precision of these methods is limited only by the regularity of the solution, in contrast to the finite difference and finite element methods. The approximation is based primarily on the weak formulation of the continuous problem. Test functions are polynomials
