In the maximum directed cut problem we are given as input a directed graph $G = (V, A)$. Each arc $(i, j)\in A$ has a nonnegative weight $w_{ij} \geq 0$. The goal is to partition $V$ into two sets $U$ and $W = V \setminus U$ so as to maximize the total weight of the arcs going from $U$ to $W$ (that is, arcs $(i, j)$ w... | The randomized 1/4-approximation algorithm for the maximum directed cut problem is as follows:
1. Randomly select a partition $U$ and $W$ of $V$ into two sets.
2. Compute the total weight of the arcs going from $U$ to $W$.
3. Return the total weight computed in step 2.
To prove that this algorithm is a 1/4-approximat... | Let $G = (V, A)$ be a directed graph with $|V| = n$ and $|A| = m$. We will give a randomized 1/4-approximation algorithm for the maximum directed cut problem. Let $U$ be the set of vertices chosen by the algorithm, and let $W = V \setminus U$.
The algorithm works as follows:
1. Randomly select a vertex $u \in V$ with... | [
