In computability theory, the halting problem is the problem of
determining, from a description of an arbitrary computer program and an
input, whether the program will finish running, or continue to run
forever. https://en.wikipedia.org/wiki/Halting_problem

// Simplified Linz Ĥ (Linz:1990:319)
// Strachey(1965) CPL translated to C
void P(u32 x)
{
if (H(x, x))
HERE: goto HERE;
}

int main()
{
Output("Input_Halts = ", H((u32)P, (u32)P));
}

A simulating halt decider H correctly decides that its input (P,P) never
reaches it final state.

This same statement equally applies to the Peter Linz proof when Ĥ is
applied to its own Turing Machine description ⟨Ĥ⟩ as shown in my paper.
