A language is said to be Decidable if there is a Machine that will accept strings in the language and reject strings not in the language. 2. A Language is called Turing Recognizable if some Turing Machine recognizes it.
What is the difference between decidable and recognizable?
If L is decidable, then L is recognized by a TM M that halts on all inputs. Note that, L might be recognized by other TM M' that does not always halt. If L is recognizable, then there might be such TM M that recognizes L but run forever, rather than rejecting, some inputs not in L.
What does it mean when a language is recognizable?
A language is Recognizable iff there is a Turing Machine which will halt and accept only the strings in that language and for strings not in the language, the TM either rejects, or does not halt at all.
