WebbDefinition. Theorem. ACCEPTTMis not computable. Proof. The reasoning is by contradiction. Assume that ACCEPTTMis computable. It will suffice to derive a contradiction. Since, by assumption, ACCEPTTMis computable, there must be some Turing machine Athat solves it. That is, (1) φA(‹M›, s) = true ⇔ φM(s) = true

Webb25 juni 2012 · The turing machine accepts all the language even though they are recursively enumerable. Recursive means repeating the same set of rules for any number of times and enumerable means a list of elements.

"Webb16 nov. 2014 · 1 Answer. 1. A language is nothing but a set of strings. So, a TM can accept multiple languages (if a TM accepts a language any subset of that language is also accepted by the TM). So, the 26 questions seems wrong- it should be language "decided by" or "recognized by" and not "accepted by". For accepted by, we can give … " - Language acceptance by tm

WebbAs far as the material discussed in this class note, there is no difference between these two definitions of "accept". A language is a phrase structure (type 0) langauage if and only if it is Turing-acceptable in either sense and it has no effects on decidablility. WebbThe time taken by a multitape TM to simulate nsteps of a computer is O(n3), so the time taken by a single-tape TM to simulate nsteps is O(n6). A language that is not c.e. (Section 9.1) A language is computable if it is accepted by some Turing machine that always halts. Problems correspond to languages; problem instances correspond to strings.

WebbFinding Unsolvable Problems We can use the fact that L D ∉ RE to show that other languages are also not RE. General proof approach: to show that some language L is not RE, we will do the following: Assume for the sake of contradiction that L ∈ RE, meaning that there is some TM M for it. Show that we can build a TM that uses M as a … WebbLecture 36 - Finiteness of TM Description, TM Configuration, Language Acceptance: Lecture 37 - Notion of Non-acceptance or Rejection of a String by a TM, Multitrack TM: Lecture 38 - Simulation of Multitape TMs by Basic Model, Nondeterministic TM, Equivalence of NDTMs with Deterministic TMs
