### Hitting edges in graphs at random and let them die with honor

Let $G=(V,E)$ be a finite simple 2-connected graph. Let $B\subseteq E$ be a set of bad edges of size $k:=|B|$. For each edge $e\in E$ we toss a fair coin ($p=1/2$) and if the outcome is head, we hit ...

### Expected size of the min-cut, under edge perturbations

Suppose we have a graph $G(V, E)$. Assume that the min-cut of this graph is given $C=(A/B)$ and denote the size of the cut with $|C|$. Create a random modification of the graph: Drop each ...
If I must connect: $$2^k$$ terminals in a Steiner Tree choosen randomly and connect them with the cheapest component; "loss - contracting algorithm" is a good way? Or is an "Iterative Randomized ...
### To find OR of $\sqrt{n}$ numbers each of $n$ bits?
Given $\sqrt{n}$ numbers of $n$ bits each. I need to find its OR and store it at another number RESULT of $n$ bits. Trivially it can be done in $\mathcal{O}(n \sqrt{n})$ time, or \$\mathcal{O}(n \sqrt{...
