What is decidable language with example?
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-Acceptable. A decision problem P is decidable if the language L of all yes instances to P is decidable.Are all P languages decidable?
Not all languages are decidable. We have shown that no algorithm is possible that, given a program p and data d, checks whether p halts on d. In language terms, this means that the set of all pairs (p, d) for which p halts on d is not decidable. We will denote this set by H and call it a halting set.Will the TM accept 00000?
For accepted by, we can give any language whose strings take the TM to final state. {00}, {000, 0000} etc are examples. "Decided by" forces the TM to reject any string not in L while "recognized by" forces the TM to accept all strings in L and not accept (reject or loop forever) any string not in L.- E(dfa) is a decidable language. Proof: A DFA accepts some string iff reaching an accept state from the start state by >traveling along the arrows of the DFA is possible. To test this condition, we can design a >TM T that uses a marking algorithm similar to that used in Example 3.23. T= "On input , where A is a DFA: 1.
