WebExercise 1 (HMU 9.3.1). Show that the set of Turing machine codes for TMs that accept all inputs that are palindromes (possibly along with other inputs) is undecidable, that is, show that the language L= fhMi: 8w2 ;(w= wR =)w2L(M))g is undecidable, where wR denotes the reverse of the string w. Solution. Web1. Let. PAL TM = { M is a Turing machine that accepts only palindromes}.. Remember that denotes the string that represents a machine M. Show that PAL TM is undecidable using a direct argument. By a "direct argument," what we mean is something that provides an explicit reduction and does not take recourse to Rice's theorem.

WebA language is called Decidable or Recursive if there is a Turing machine which accepts and halts on every input string w.Every decidable language is Turing-Acceptable.
