On the covering of left-recursive grammars

Research output: Book/Report › Report › Other research output

Abstract

In this report we show that some prevailing ideas on the elimination of left recursion in a context-free grammar are not valid. An algorithm and a proof are given to show that every proper context-free grammar is covered by a non-left-recursive grammar. Some additional results concerning parsing and covering strict determinisitc grammars are also given.
