Krtolica, Predrag V.; Stanimirović, Predrag S. Symbolic derivation without using expression trees. (English) Zbl 1041.68133 Yugosl. J. Oper. Res. 11, No. 1, 61-75 (2001). The authors present an algorithm which is done on the reverse Polish notation of an input formula and produces the reverse Polish notation of its derivative. In that way an expression tree is not used which reduces memory and time costs.
