Webmars. Knuth’s algorithm is provably efficient: it requires at most 0(n G ) units of time, where G is the size of (i.e. the number of symbols in) G and n is the length of the string to be parsed. This is often significantly better than the 0(n3 G 2) worst case time required by standard parsing algorithms such as the Earley algorithm.
