Hello. I am a mathematics student at the University of Copenhagen. I would like to understand quantum computation, and therefore I have started out writting a...
First, I'm not an expert in this field, so everything I write might be wrong. If you think so, I'd like to ask you to correct me. ... The NTM for deciding...

... As far as I can say, this is not a big difference -- n has a factor < k iff it has a prime factor < k (clearly, a prime factor is a factor and if n has a...
consider the language infinite = { <M>; M accepts infinetly many words} show that: a) Atm <=m infinite b)Atm_c <=m infinite c) Neither infinite <=m Atm nor...
... This was meant as a help to prove FACTORIZATION is also in co-NP. Here it is actually sufficient to use Pratt's result that PRIMALITY is in NP. And as for...

... Hey there Piotr! I hope to be a bit more active in the group for now (I couldn't exactly be _less_ active). Thanks to everyone who has kept posting (and...
... That's very interesing. Though I'm rather in the opposition -- yet I was unable to understand the power of interaction. Therefore can't wait for the...
salespeople can be a bit persistent, I'd like to solve the traveling salesman problem using a 4-headed Turing Machine and prove that it is NP complete....

That is still an open problem, that is whether or not the traveling salesman problem is in P. The Church Turing thesis states that any algorithmic procedure...
The fact of the matter is that the TSP problem is not in P, therefore if it is not in the class P then it obviously can't be in class NP, based on the ...
With all due respect, please brush up on introductory complexity theory - you're understanding of the complexity world is quite a bit off. I will try to clear...

Hi, I need help to solve the following questions: 1. Show that {<M, w, q> | Turing Machine M reaches state q on input w} is not recursive. 2. Show that {<M,...
