WebThe algorithm starts with all the T i;i’s and then computes T i;i+k’s for k from 0 to n 1. That is, the algorithm calculates the set of variables that generate all the substrings of length 1, 2 and so on until n. The algorithm pseudocode is given below. Algorithm 1 CYK Algorithm. Given string w = a 1:::a n and CFG G. Checks if w 2L(G).

In computer science, the Cocke–Younger–Kasami algorithm (alternatively called CYK, or CKY) is a parsing algorithm for context-free grammars published by Itiroo Sakai in 1961. The algorithm is named after some of its rediscoverers: John Cocke, Daniel Younger, Tadao Kasami, and Jacob T. Schwartz. It employs bottom … See more The dynamic programming algorithm requires the context-free grammar to be rendered into Chomsky normal form (CNF), because it tests for possibilities to split the current sequence into two smaller sequences.
