Has Plummer's open problem on the cyclic connectivity of planar graphs been solved?
$\DeclareMathOperator\cl{cl}$The cyclic edge connectivity $\cl(G)$ is the size of a smallest cyclic edge cut, i.e., a smallest edge cut $F$ such that $G-F$ has two connected components, each of which ...

Random Optimization on Graphs: Minimum Cut
Consider a complete graph on $n$ vertices. To each edge, $(i,j)$, we assign a weight, $W_{ij}$, which comes from some known distribution iid. Then, we ask the following question. Among all (weighted) ...

expected number of edges for fixed min cut
It is known that a graph $G=(V,E)$ with $n$ nodes and min cut $k$, must have at least $\frac{1}{2}nk$ edges.
Are there any tighter bounds or expectations I can place on $|E|$ if I assume that $G$ ...
