What is the easiest randomized algorithm to motivate to the layperson?
If you're willing to flex a bit on "non-trivial to get an efficient deterministic algorithm" (or at least on the definition of "non-trivial"), max-cut is a very easy one. Given a graph $G=(V,E)$, the …

Theorems about the directed bandwidth of a rooted tree?
Let $T$ be a rooted tree with root $r$. Say an ordering $v_1,\ldots,v_n$ of the vertices of $T$ is a search order if $v_1=r$ and for all $2 \leq i \leq n$, there is $j < i$ such that $v_j$ is the pare …
