Theory of Computation

"Introduction to Theory of Computation" offers a comprehensive overview of the foundational concepts in computation. It begins by defining computation as the process of executing a sequence of operations based on algorithms to achieve specific outcomes, encompassing both natural and artificial processes. The historical development of computation, from early computational devices like the abacus to the advent of mechanical and electronic computers, is explored, highlighting key milestones such as the invention of the transistor and the development of the Internet. The chapter introduces essential concepts such as algorithms, data structures, and formal languages, along with models of computation including finite automata, pushdown automata, and Turing machines.
