If I have a machine, call it machine 1, that is able to solve a problem: it's just a machine, not per se a Turing machine. It can solve one specific problem. If this exact same problem can be solved on a Universal Turing Machine, then is my original machine, 1, a Universal Turing Machine too?
This does not hold for all problems, which is already ansered. Are there any problems which have this described property at all? If it is absolutely not true, then why?
Can someone give an example of a problem to be solved. If this problem is solved by my original machine, 1, definately makes this a Universal Turning Machine? Or does such a problem not exists? If it doesn't exists, why?
I'm very interested, but can't figure it out... Thanks.
Edit: made the question more clear.
