Introduction The concept of Chomsky Classification was developed by linguist Noam Chomsky in 1956. The Chomsky Classification is also known as the Chomsky hierarchy. Definition The Chomsky Classification is a hierarchy that categorizes grammars and languages into four types based on their generative power and computational models. The Chomsky hierarchy is a classification of Read more…
Introduction The Turing Machine (TM) was proposed by Alan Turing (1936). Definition A Turing Machine is an abstract machine or theoretical computational model that manipulates symbols on an infinite tape according to a set of rules. A Turing Machine is defined in a 7-tuple form: M=(Q,Σ,Γ,δ,q0,B,F) where, Q = Finite set of Read more…
Introduction A Context-Free Grammar (CFG) is a formal system that provides a precise way to define valid strings in a language. Definition A Context-Free Grammar (CFG) is a formal grammar used to define context-free languages, where each production rule has a single non-terminal on the left-hand side. A language is Read more…
