### If g is a PRG and f is a OWF, is G'(x) = f(g(x)) a PRG?

Just like the title states. If I have a pseudo-random generator $g\colon \Sigma^n \rightarrow \Sigma^{2n}$ and a one-way function $f$, is $g'(x)=f(g(x))$ a pseudo-random generator? And why? My ...

### What is and amplification factor in pseudo-random generators?

I can't seem to find an answer to this. For instance, I have this question: Show that, if $P=NP$, there aren't any pseudo-random generators (even with amplification factor $n+1$). My gut tells me this ...

### How likely is for a pseudorandom number generator to generate a long sequence of similar numbers?

How likely is for a pseudorandom number generator to generate a long sequence of similar numbers? "Similar numbers" could be same numbers, or numbers from a given range. For example, if we consider ...
