摘要：
An exhaustive classical symmetry analysis is carried out for the general class of nonlinear diffusion-convection in (1 + 1) dimensions, and the corresponding optimal system is found for every case with extra symmetries. The invariants are found for the nontrivial generators of each optimal system, and reduction is made to an ordinary differential equation. New symmetries and new reductions are found.
