Simple Odd ,-Cycle Inequalities for Binary Polynomial Optimization,instance is a cycle hypergraph. We introduce a weaker version, called simple odd .-cycle inequalities, for which we establish a strongly polynomial-time separation algorithm for arbitrary instances. These inequalities still have Chvátal rank 2 in general and still suffice to describe the multilinear polytope for cycle hypergraphs.

Intersecting and Dense Restrictions of Clutters in Polynomial Time,of that a dense clutter with no proper dense minor is either a delta or the blocker of an extended odd hole. This simplification reduces the running time of the algorithm for finding a delta or the blocker of an extended odd hole minor from previously . to . filter oracle calls.

,The Simultaneous Semi-random Model for TSP, is in the context of the Euclidean Traveling Salesman Problem (TSP) in the plane, where local search performs extremely well in practice even though it only achieves an . worst-case approximation ratio. In such cases, a natural alternative approach to worst-case analysis is to analyze the performan
