Halt the machine
WebStep1: Assume we can create a machine called HM (P, I), where HM is the Halting machine, P is the program, and I is the input. After receiving both inputs, the machine HM will output whether or not the program P terminates.

If we take the union of any c.e. subset of halting TMs and any c.e. subset of non-halting TMs, the result will be set of TMs for which the halting problem is decidable (run both machines in parallel, if the first one accept the TM halts, if the second one accepts then the machine does not halt).

Q is a finite set of states, including the halt state, h. Λ is an alphabet which includes the blank symbol, #. q0 ∈ Q is the start state. δ: (Q∖{h}) × Λ → Λ × {L, R} × Q is the transition function. The fact that δ(q, σ) = (τ, d, r) means that when the Turing ...
