摘要: Two classes of restricted top-down parsing algorithms modeling “recursive descent” are considered. We show that the smaller class recognizes all deterministic context free languages, and both can be simulated in linear time on a random access machine. Certain generalizations these shown equivalent to larger class. Finally, it is has property loops other “failures” always eliminated.
