Maximum Directed Cuts in Graphs with Degree Constraints
The Max Cut problem is an NP-hard problem and has been studied extensively. Alon et al. studied a directed version of the Max Cut problem and observed its connection to the Hall ratio of graphs. They proved, among others, that if an acyclic digraph has m edges and each vertex has indegree or outdegree at most 1, then it has a directed cut of size at least 2m/5. Lehel et al. extended this result...
متن کاملMaximum directed cuts in digraphs with degree restriction
For integers m, k ≥ 1, we investigate the maximum size of a directed cut in directed graphs in which there are m edges and each vertex has either indegree at most k or outdegree at most k.
متن کاملk-forested choosability of graphs with bounded maximum average degree
A proper vertex coloring of a simple graph is $k$-forested if the graph induced by the vertices of any two color classes is a forest with maximum degree less than $k$. A graph is $k$-forested $q$-choosable if for a given list of $q$ colors associated with each vertex $v$, there exists a $k$-forested coloring of $G$ such that each vertex receives a color from its own list. In this paper, we prov...
متن کاملMaximum directed cuts in acyclic digraphs
It is easily shown that every digraph with m edges has a directed cut of size at least m/4, and that 1/4 cannot be replaced by any larger constant. We investigate the size of a largest directed cut in acyclic digraphs, and prove a number of related results concerning cuts in digraphs and acyclic digraphs.
متن کاملClustering by weighted cuts in directed graphs
In this paper we formulate spectral clustering in directed graphs as an optimization problem, the objective being a weighted cut in the directed graph. This objective extends several popular criteria like the normalized cut and the averaged cut to asymmetric affinity data. We show that this problem can be relaxed to a Rayleigh quotient problem for a symmetric matrix obtained from the original a...
