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 algorithm is …

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 substring spanning …

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 automata...

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 and a string s, …

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 context-free …

The CYK algorithm (named for Cocke, Young, and Kasami, each of whom develeped it independently of the others in the mid-1960's) solves the membership problem for context-free grammars in Chomsky …

May 2, 2025 · Invented by J. Cocke, D.H. Younger, and T. Kasami. Requires \ (|w|^3\) steps to parse string \ (w\). Dynamic Programming remembers the answer to small subproblems so that it won’t …

The CYK algorithm is a parsing technique for context-free grammar that checks if a string can be derived from a given grammar, requiring the grammar to be in Chomsky Normal Form (CNF).

Theorem The CYK Algorithm correctly computes X i j for all i and j; thus w is in L(G) if and only if S is in X1n. The running time of the algorithm is O(n3).
