The problem of finding the Minimum Feedback Arc Set with triangle inequalities can be solved as a special case of the minimum vertex cover in hypergraphs with edges of size at most 3. This discovery allows for the development of new approximation algorithms and offers a different perspective on how to approach this problem.
