Lecture Notes Theory of Computation
This lecture note from S R Engineering College offers a detailed introduction to key concepts in the Theory of Computation. It begins with Properties of Binary Operations, exploring fundamental mathematical operations and their essential properties like associativity and commutativity. The section on Concatenation Properties covers how strings can be joined and the characteristics of such operations, including associativity and the identity element. Finite Automata are thoroughly discussed, explaining both deterministic and nondeterministic (NFA) models, and their role in recognizing regular languages. The notes also cover Formal Languages, categorizing them into regular, context-free, context-sensitive, and recursively enumerable types based on complexity. Finally, the Pumping Lemma is introduced as a critical tool for proving the non-regularity and non-context-freeness of languages by demonstrating how strings in these languages can be decomposed and manipulated.

Theory of Computation by Frank Stephan
Frank Stephan's detailed lecture notes on the theory of computation cover quite a wide spectrum of issues. The document starts with the basics of sets and regular expressions, then goes ahead to grammars and the Chomsky hierarchy, helping one in understanding the structure of languages. Then it discusses finite automaton and nondeterministic finite automata, giving all details about the processing of strings by these models. The notes also treat the composition of languages, normal forms, and algorithms used in computation. Membership testing, whether deterministic or nondeterministic, is also explained, together with the proof of how models of computation handle language recognition. Finally, the approach is important when considering complexity, the problems that turn out undecidable, showing thus the intrinsic limits of computation. This is an important resource concerning formal languages, automata theory, and basic bounds of computability.

Lecture Notes of Introduction to the Theory of Computation
Authored by Margaret Fleck and Sariel Har Peled, this is a wide set of lecture notes on the theory of computation. These start with the very basic objects such as strings and deterministic finite automata (DFAs) before moving up to regular expressions and nondeterministic automata. This course covers formal language theory, including some advanced topics such as Turing machines, decidability, and several language-related problems. It is intended that these notes afford a comprehensively broad yet deep exploration of the formal languages, automata, and computability material with an excellent bibliography that creates interest among students and researchers.

Introduction to the Theory of Computing
Introduction to the Theory of Computing is a course that undertakes an intensive study of the underpinnings of the theory of computation. Beginning with mathematical foundations, the course moves into regular operations and expressions, and then into proofs on languages being nonregular and other further treatments on regular languages. Other important topics include parse trees, ambiguity, Chomsky normal form, pushdown automata, and Turing machines. Further, the PDF discusses various types of Turing machines, the stack machine model, and undecidable languages, making it a great starting point in the topic of computability.

Theory of Computation by Kyle Burke
This book surveys some of the most relevant theoretical concepts with computational models. The limits of computation, undecidability of the Halting Problem, several automata models, including both deterministic and nondeterministic finite-state automata, pushdown automata, and Turing machines, are introduced. The ending is dedicated to computational complexity, with NP-Completeness, approximation algorithms, and hardness of approximation.

Introduction to Theory of Computation by Wikiversity
This is an all-inclusive course on computational theory provided in this online resource by Wikiversity. It begins with Finite State Machines–their definitions, operations, and minimization techniques. The notes also cover closure and nondeterminism—how these properties may affect computational models. Their discussion greatly involves the Pumping Lemma, proving language property. The book also surveys Context-Free Languages and their connection to Compilers and introduces Pushdown Machines emphatically and focuses on their importance in parsing. It contains important material on the CYK algorithm for parsing and the more basic problems of Undecidability. It also surveys Turing Machines, the Halting Problem, and more general areas of Complexity Theory, including Quantified Boolean Formulae, Savitch's Theorem, and Space Hierarchy. The notes end with the Recursion Theorem, and it can be considered as a landmark in the theoretical study of the science of computers.

Introduction to Theory of Computation Lecture Notes
These lecture notes give an introduction to the more fundamental parts of the theory of computation and begin by presenting finite automata: starting with deterministic and nondeterministic finite automata, their equivalence, and practical implications of these concepts. The lecture notes include sections on regular expressions and their relationship to finite automata, non-regular languages, and the Pumping Lemma to prove non-regularity. Myhill-Nerode Theorem: For understanding recognition of languages. The notes go further to present context-free languages, including their ambiguity and properties of closure. The pumping lemma for context-free languages is also discussed, while decidable and recognizable languages are informed by a deep underpinning in computational theory.
