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. [1][2] The …

Jul 15, 2025 · How does the CYK Algorithm work? For a string of length N, construct a table T of size N x N. Each cell in the table T [i, j] is the set of all constituents that can produce the …

In this step-by-step tutorial, I walk you through the CYK algorithm with a real example, explaining each part of the process and making parsing easy to understand—even if you’re new to …

CYK Algorithm Handout Every Context-free language can be decided in polynomial time, using the CYK (Cook, Younger, and Kura-towski) dynamic programming algorithm.

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 …

Example (The CYK Parsing Algorithm) The CYK algorithm is much easier to perform if we use an n n table. The entry in row i, column j is the set Vij. We begin by initializing the diagonal …

The Cocke-Younger-Kasami (CYK) algorithm is a parsing algorithm for context-free grammars. It determines whether a string can be generated by a grammar and, if so, how it can be generated.

It is one of the earliest recognition and parsing algorithms. The standard version of CKY can only recognize languages defined by context-free grammars in Chomsky Normal Form (CNF). It is …

Mar 14, 2024 · The Cocke–Younger–Kasami-Algorithm (CYK or CKY) is a highly efficient parsing algorithm for context-free grammars. This makes it ideal to decide the word-problem for …

We check if (i, k) cell contains B and (k + 1, j) cell contains C: 13. If so, we put A in cell (i, j) of our table. 14. We check if S is in (1, n): 15. If so, we accept the string. 16. Else, we reject.
