Cut-Matching Games on Directed Graphs
نویسنده
چکیده
We give O(log n)-approximation algorithm based on the cut-matching framework of [10, 13, 14] for the computing the sparsest cut on directed graphs. Our algorithm uses only O(log n) single commodity max-flow computations and thus breaks the multicommodity-flow barrier for computing the sparsest cut on directed graphs.

Approximating Multicut and the Demand Graph
In the minimum Multicut problem, the input is an edgeweighted supply graph G = (V,E) and a demand graph H = (V, F ). Either G and H are directed (Dir-MulC) or both are undirected (Undir-MulC). The goal is to remove a minimum weight set of supply edges E′ ⊆ E such that in G − E′ there is no path from s to t for any demand edge (s, t) ∈ F . Undir-MulC admits O(log k)-approximation where k is the ...
متن کاملThe topological ordering of covering nodes
The topological ordering algorithm sorts nodes of a directed graph such that the order of the tail of each arc is lower than the order of its head. In this paper, we introduce the notion of covering between nodes of a directed graph. Then, we apply the topological orderingalgorithm on graphs containing the covering nodes. We show that there exists a cut set withforward arcs in these...
متن کاملOf Stable Marriages and Graphs, and Strategy and Polytopes
This expository paper develops the principal known results (and some new ones) on the stable matchings of marriage games in the language of directed graphs. This both unifies and simplifies the presentation and renders it more symmetric. In addition, it yields a new algorithm and a new proof for the existence of stable matchings, new proofs for many known facts, and some new results (notably co...
متن کاملThe Tractability of the Shapley Value over Bounded Treewidth Matching Games
Matching games form a class of coalitional games that attracted much attention in the literature. Indeed, several results are known about the complexity of computing over them solution concepts. In particular, it is known that computing the Shapley value is intractable in general, formally #P-hard, and feasible in polynomial time over games defined on trees. In fact, it was an open problem whet...
متن کاملMatching Integral Graphs of Small Order
In this paper, we study matching integral graphs of small order. A graph is called matching integral if the zeros of its matching polynomial are all integers. Matching integral graphs were first studied by Akbari, Khalashi, etc. They characterized all traceable graphs which are matching integral. They studied matching integral regular graphs. Furthermore, it has been shown that there is no matc...
