Question: We showed that a language is Turing recognizable iff some enumerator enumerates it. Why didnt we use the following simpler algorithm? Here s 1 ,

We showed that a language is Turing recognizable iff some enumerator enumerates it. Why didnt we use the following simpler algorithm? Here s₁, s₂, s₃, is a listing of strings in *.

E = Ignore the input.

Repeat the following for i = 1, 2, 3,

Run M on s_i

If it accepts the print out s_i
