This set of tutorials goes into the heart of the theory of computer science with formal languages and automatons, computability, and complexity. Topics to be discussed are regular and contextfree languages, finite automata, and pushdown automata. Consequently, resulting tutorials treat topics like Turing machines, Churchs thesis, and the problem of undecidability, whose examples include the and quot,halting problem and quot, in the exploration of the limits of computability. They look into complexity classes such as P, NP, and PSPACE, look into NPcompleteness, or provide an indepth treatment along with a wide introduction to the theoretical foundations of computer science.

This pdf begins with an overview of resources, organization and motivation and preview of CS theory covering the Limits of Computation, the Undecidability of the Halting Problem.The Automata and Machines including Deterministic and Nondeterministic Finitestate Automata, Pushdown Automata, and Turing Machines and Language Classes. Finally focus shifts to Computational Complexity, discussing NPCompleteness, Approximation Algorithms, and the Hardness of Approximation.

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, nonregular languages, and the Pumping Lemma to prove nonregularity. MyhillNerode Theorem, For understanding recognition of languages. The notes go further to present contextfree languages, including their ambiguity and properties of closure. The pumping lemma for contextfree languages is also discussed, while decidable and recognizable languages are informed by a deep underpinning in computational theory.
