Hardness for Hypergraph Coloring
We show that it is quasi-NP-hard to color 2-colorable 8-uniform hypergraphs with 2(logN) 1/10−o(1) colors, where N is the number of vertices. There has been much focus on hardness of hypergraph coloring recently. In [17], Guruswami, H̊astad, Harsha, Srinivasan and Varma showed that it is quasi-NP-hard to color 2-colorable 8-uniform hypergraphs with 22Ω( √ log logN) colors. Their result is obtain...
متن کاملApproximate Hypergraph Coloring
A coloring of a hypergraph is a mapping of vertices to colors such that no hyperedge is monochromatic. We are interested in the problem of coloring 2-colorable hypergraphs. For the special case of graphs (hypergraphs of dimension 2) this can easily be done in linear time. The problem for general hypergraphs is much more difficult since a result of Lovász implies that the problem is NP-hard even...
متن کاملTesting Hypergraph Coloring
In this paper we initiate the study of testing properties of hypergraphs. The goal of property testing is to distinguish between the case whether a given object has a certain property or is “far away” from the property. We prove that the fundamental problem of `-colorability of k-uniform hypergraphs can be tested in time independent of the size of the hypergraph. We present a testing algorithm ...
متن کاملHypergraph coloring complexes
The aim of this paper is to generalize the notion of the coloring complex of a graph to hypergraphs. We present three different interpretations of those complexes-a purely combinatorial one and two geometric ones. It is shown, that most of the properties, which are known to be true for coloring complexes of graphs, break down in this more general setting, e.g., Cohen-Macaulayness and partitiona...
متن کاملGeombinatorial Mixed Hypergraph Coloring Problems
Can you color Rn so that point sets of one sort are never monochromatic, while point sets of another sort always are? If so, how many colors did you use, and can you do the job with more or fewer colors?
