Discuss Automata Theory, Automata Theory is a branch of computer science that deals with designing abstract selfpropelled computing devices that follow a predetermined sequence of opera…Read More
Rice Theorem, Rice theorem states that any non-trivial semantic property of a language which is recognized by a Turing machine is undecidable. A property, P, is the language …Read More
Post Correspondence Problem, The Post Correspondence Problem (PCP), introduced by Emil Post in 1946, is an undecidable decision problem. The PCP problem over an alphabet ∑ is stated as fo…Read More
Language Decidability, A language is called Decidable or Recursive if there is a Turing machine which accepts and halts on every input string w. Every decidable language is Turing-Acc…Read More
Undecidable Languages, For an undecidable language, there is no Turing Machine which accepts the language and makes a decision for every input string w (TM can make decision for some …Read More
Turing Machine Halting Problem, Input − A Turing machine and an input string w.…Read More
Non-Deterministic Turing Machine, In a Non-Deterministic Turing Machine, for every state and symbol, there are a group of actions the TM can have. So, here the transitions are not deterministic.…Read More
Semi-Infinite Tape Turing Machine, A Turing Machine with a semi-infinite tape has a left end but no right end. The left end is limited with an end marker.…Read More
