How does oracle work here?
Does anyone have information on how oracle for functions works here? I have two ideas, though there sure are more: Of course there are many possible variations on technical details which could be going on here. LittlePeng9 (talk) 15:39, May 26, 2015 (UTC)
 * 1) Machine, after writing down numbers \(a,b\), requests the oracle to say if \(f(a)=b\),
 * 2) Machine provides input and then oracle somehow writes down the output.
