带三角不等式的反馈弧集问题是一个顶点覆盖问题
The Feedback Arc Set Problem with Triangle Inequality is a Vertex Cover Problem
摘要：
我们考虑（优先约束）最小反馈弧集问题的三角不等式的权重，发现重要的应用在排序问题的不一致信息。我们提出了一个令人惊讶的结构洞察力表明，这个问题是一个特殊的情况下，最小顶点覆盖的超图的边的大小最多为3。这一结果导致组合近似算法的问题，并开辟了道路，研究问题的顶点覆盖问题。
英文摘要：
We consider the (precedence constrained) Minimum Feedback Arc Set problem with triangle inequalities on the weights, which finds important applications in problems of ranking with inconsistent information. We present a surprising structural insight showing that the problem is a special case of the minimum vertex cover in hypergraphs with edges of size at most 3. This result leads to combinatorial approximation algorithms for the problem and opens the road to studying the problem as a vertex cover problem.
