Let’s have our grammar rules as well alongside its CNF.
WebThe importance of the CYK algorithm stems from the fact that it constructively proves that the membership problem for context-free languages is decidable (see also: theory of computation) and the fact that it does so quite efficiently. The worst case asymptotic time complexity of CYK is Θ(n 3), where n is the length of the parsed string. This ...
