摘要

Armed with the computer algebra system Maple, using a direct algebraic substitution method, we obtain Lie point symmetries, Lie symmetry groups and the corresponding symmetry reductions of one component nonlinear integrable and nonintegrable equations only by clicking the 'Enter' key. Abundant (1+1)-dimensionai nonlinear mathematical physical systems are analysed effectively by using a Maple package LieSYMGRP proposed by us.
