WebEssentially, instead of storing a sequence of sets of items like in the original algorithm, the modified algorithm just stores pointers back to sets of reachable items. The worst-case run time performance of the Earley parsing algorithm is cubic in the length of the input, but for large classes of grammars it is linear. WebEarley’s parsing algorithm [1, 2] is a general algorithm, capable of parsing according to any context-free grammar. (In comparison, the LALR(1) parsing algorithm used in Yacc …
