WebT = “On input hM,Ri, where M is a DFA and Ris a regular expression: 1. Convert Rinto a DFA DR using the algorithm in the proof of Kleene’s Theorem. 2. Run TM decider F from Theorem 4.5 on input hM,DRi. 3. If F accepts, accept. If F rejects, reject.” 2. Consider the decision problem of testing whether a CFG generates the empty string. Web{x x ≠ M, w for any TM Mand string w, or Mis a TM that does not accept w} Cheating With Math As a mathematical simplification, we will assume the following: Every string can be decoded into any collection of objects. Every string is an encoding of some TM M. Every string is an encoding of some TM Mand string w. Can do this as follows:
