Since the Halting Problem is undecidable, and we have shown that if we had a solution for the given decision problem, we could solve the Halting Problem, we conclude that the given decision problem is also undecidable.
To show that the given decision problem is undecidable, we can reduce the Halting Problem to it.
The Halting Problem is the problem of determining whether a given Turing machine halts on a specific input. We know that the Halting Problem is undecidable, which means there is no algorithm that can solve it for all possible inputs.
Now, let's assume we have an algorithm that can solve the decision problem given a Turing machine T and a non-halting state q. We will use this algorithm to solve the Halting Problem.
Given an input (T, w) for the Halting Problem, we can construct a new Turing machine T' as follows:
Modify T to include a new state q' that is non-halting.
Modify T to transition to state q' whenever it reaches a non-halting state.
Modify T to accept the input w.
Now, we can use our algorithm for the given decision problem on (T', q'). If the algorithm determines that T' enters state q' when it begins with a blank tape, then T halts on input w. Otherwise, T does not halt on input w.
