- What is decider? - Computer Science Stack Exchange
Intuitively, a decider should be a Turing machine that given an input, halts and either accepts or rejects, relaying its answer in one of many equivalent ways, such as halting at an ACCEPT or REJECT state, or leaving its answer on the output tape A similar concept is a total Turing machine, which is a machine that halts on every input
- turing machines - Visualizing a Non Deterministic Decider - Computer . . .
Further, I also know that a Decider is a TM that halts on all possible inputs Now, my question is how can I visualize a Non determistic Decider? Does a non-determistic decider mean a TM where All the copies must halt, (OR) At-least one copy halts Kindly explain in detail why so Thanks
- Confused about definition of a non-deterministic decider
Fallowing are some definitions from book quot;introduction to theory of computation quot; by sipser a nondeterministic turing machine is a decider if all its computation branches halt on all inp
- computability - Constructing a decider for a language - Computer . . .
I'm confused about the idea of constructing a decider for a language and i need some help with it For example, if i have an enumerator M1 for a language L and another enumerator M2 for the compl
- Turing Machines: What is the difference between recognizing, deciding . . .
See comment on OP's answer here, then the answer by Jan Hudec : What is the difference between a TM accepting and deciding a language? I have also seen the definition of total decider to mean, the Turing machine halts on all inputs Is this all inputs in the language the Turing Machine is defined over?
- Finding a decider - Computer Science Stack Exchange
Find a decider for Ln L n For the right hand side, I thought I could check the length of 𝑤 and then simulate the recognizer that recognizes L2 L 2 until it accepts
- Does a non deterministic Turing machine which is a decider halt on all . . .
Does a non deterministic Turing machine which is a decider halt on all branches for all inputs?? I know it must halt on all branches for a string not in language, but for a string in language, NDTM requires only one accepting branch so even if some other branch is infinite, NDTM will still accept the string
- turing machines - Whats the difference between an oracle and a decider . . .
I'm learning about Turing reductions at the moment and I'm just wondering is there any difference between an oracle and a decider, As they seemingly do the exact same thing I understand the point
