\paragraph{Reminder.}
Homework must be typeset with \LaTeX\ preferred. Make sure you understand the course collaboration and honesty policy before beginning this assignment. Collaboration is permitted, but you must write the solutions {\em by
yourself without assistance}. You must also identify your
collaborators. Assignments missing a collaboration statement will not be accepted. Getting solutions from outside sources such as the
Web or students not enrolled in the class is strictly forbidden.

\begin{problem}[Term Paper] Give the paper you are reviewing a careful reading and start thinking about the structure and content of your review. (A draft of your review is due on Nov. 21, so don’t delay!)

\begin{problem}[$\NP, \BPP$, and $\RP$] \hfill
\begin{enumerate}[(a)]

\item Suppose $\NP \subseteq \BPP$. Show that $\mathprob{SearchSAT}$ can be solved in randomized polynomial-time. That is, show that there is a probabilistic poly-time algorithm $M$ such that for all satisfiable CNF formulas $\varphi$, we have that $M(\varphi)$ outputs a satisfying assignment to $\varphi$ with probability at least $2/3$. (7 points)

\begin{solution}
Your solution here.
\end{solution}

\item Use part (a) to conclude that if $\NP \subseteq \BPP$, then $\NP = \RP$. (5 points)

Your solution here.

\begin{problem}[Counting Cycles]
A Hamiltonian cycle in a directed graph $G$ is a cycle that visits every vertex in $G$ exactly once. Define the problem $\mathprob{\#HAM}$\footnote{I’m not so sure about sharp ham, but I like my ham with sharp cheddar.} as follows: Given a directed graph $G$, count the number of Hamiltonian cycles in $G$. It is known that $\mathprob{\#HAM}$ is $\sharpP$-complete. Use this fact to prove that $\mathprob{\#CYCLE}$ is also $\sharpP$-complete. (8 points)

\begin{solution}
Your solution here.
