decidable (or simply decidable) if there exists a TM M which decides L. • Every finite language is decidable: For example by a TM that has all the strings in ...
Every finite language is decidable: For e.g. by a TM that has all the Proof. If Atm is recognizable
study some immunity properties: for instance we prove that for every coinfinite decidable language L there exists a decidable language L′ such that L ⊆ L′ L′
▷ Every finite language is decidable. Page 10. Decidable and Recognizable Languages. Recall: Definition. A Turing machine M is said to recognize a language L
