What is decider? - Computer Science Stack Exchange
My understanding of decider is that a machine is a decider if it always halts with output $0$ or $1$ (or whatever you prefer meaning "YES" and "NO"). However, I am confused by the definition …
turing machines - Visualizing a Non Deterministic Decider
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 …

context free - Can we build a nondeterministic decider PDA using …
Yes, it is possible to do so. Although a given PDA may have $\varepsilon$ loops that can induce infinite computation, we can sidestep this by converting the PDA to a CFG, then back to a …
