WebGreat Algorithms: CYK Aaron Gorenstein September 1, 2013 Abstract The CYK algorithm, named after Cocke, Younger, and Kasami, is an algorithm for deciding if a string is in a context-free language. In particular: given a grammar G in Chomsky Normal Form and a string s, the CYK algorithm returns true exactly when s 2 L(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.
