\title{A formalisation of the Cocke-Younger-Kasami algorithm}
\author{Maksym Bortin}
\maketitle

\begin{abstract}
  The theory provides a formalisation of the Cocke-Younger-Kasami
  algorithm~\cite{Younger1967} (CYK for short), an approach to solving the
  word problem for context-free languages.  CYK decides if a word is in the
  languages generated by a context-free grammar in Chomsky normal form.
  The formalized algorithm is executable.
