One of the major challenges of the research in circuit complexity is proving super-polynomial lower bounds for de-Morgan formulas. Karchmer, Raz, and Wigderson suggested to approach this problem by proving that formula complexity behaves "as expected'' with respect to the composition of functions $f\circ g$. They showed that this conjecture, ... more >>>

Given a Boolean formula in Conjunctive Normal Form (CNF) $\phi=S \cup H$, the MaxSAT (Maximum Satisfiability) problem asks for an assignment that satisfies the maximum number of clauses in $\phi$. Due to the good performance of current MaxSAT solvers, many real-life optimization problems such as scheduling can be solved efficiently ... more >>>

Suppose Alice holds a uniformly random string $X \in \{0,1\}^N$ and Bob holds a noisy version $Y$ of $X$ where each bit of $X$ is flipped independently with probability $\epsilon \in [0,1/2]$. Alice and Bob would like to extract a common random string of min-entropy at least $k$. In this ... more >>>
