I am going through a Turing machine topic. I know about decidable, semi decidable, and decidable problems. But honestly speaking, I did not get any practical examples of Semidecidable problems. Can you please share some examples or a URL link? Is the NP problem a semidecidable problem? If yes, then it means that NP-complete problems are Recursive enumerable. Please correct me if I am wrong.
I am thankful to you.
