comment understanding the proof of knowledge
In your first question, do you mean Zero-Knowledge Proof of Knowledge? or a mere Proof of Knowledge?

comment Hamiltonicity proof of knowledge
@RickeyDemer 1.Why did you assigned 0 to $\kappa (|x|)$? 2.Why do you need a minimum-length witness? 3.$K_w$ cannot output a witness with certainity, if $P^*$ is lying then $K_w$ wouldn't be able to output a witness. 4. I don't understand your conclusion (where is it stems from?).

comment Hamiltonicity proof of knowledge
$L_R$ is the set of all $x$s s.t. there exists $y$ s.t. $(x,y)\in R$. The construction of the knowledge extractor is trivial bur what can you say about the running time requirement, which related to the knowledge error? (As I wrote in the 'question' part)

No, this is another problem that I encounter, even to find out what are the topics that I should study beforehand.

Well, that's my question.. why does the cloned is considered as a PRG? How can you prove that the cloned is a PRG as well?

And since the attacker doesn't control the input to a PRG he cannot distinguish between its output and a random string. This is my intuition, I just don't know how to prove.
