A simplified version of Aho and Ullman's algorithm  is presented for the elimination of unit productions of the form A::= B from LR(k) parsers. The algorithm does not eliminate all such unit productions, but it is applicable in practical instances not handled by Aho and Ullman's technique.
Compiling, LR(k) parsing, parser generators, parser optimization, parsing, unit production elimination.
