We consider evolution equations of the form u t = f(x, u, u x )u xx + g(x, u, u x ) and u t = u xx + g(x, u, u x ). In the spirit of the recent work of Ibragimov [Ibragimov NH. Laplace type invariants for parabolic equations. Nonlinear Dynam 2002;28:125-33] who adopted the infinitesimal method for c
