WebJul 19, 2024 · The CYK algorithm takes as input a CFG that's in Chomsky normal form. That means that every production either has the form. S → a, for some terminal a, or. S → AB, for some nonterminals A and B. Now, imagine you have a string w and you want to see whether you can derive it from a grammar whose start symbol is S.

Let’s have our grammar rules as well alongside its CNF. 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.
