Optimal Hardness of Online Algorithms for Large Independent Sets

David Gamarnik, Eren C. Kızıldağ, Lutz Warnke

We study the algorithmic problem of finding a large independent set in the Erd{ö}s-Rényi random graph . For constant and , the largest independent set has si…

The clique chromatic number of sparse random graphs

Manuel Fernandez, Lutz Warnke

The clique chromatic number of a graph is the smallest number of colors in a vertex coloring so that no maximal clique is monochromatic. In this paper, we determine the order of ma…

Two-Point Concentration of the Domination Number of Random Graphs

Tom Bohman, Lutz Warnke, Emily Zhu

We show that the domination number of the binomial random graph G_{n,p} with edge-probability p is concentrated on two values for p \ge n^{-2/3+\eps}, and not concentrated on two v…

Extreme local statistics in random graphs: maximum tree extension counts

Pedro Araújo, Simon Griffiths, Matas Šileikis +1

We consider maximum rooted tree extension counts in random graphs, i.e., we consider M_n = \max_v X_v where X_v counts the number of copies of a given tree in G_{n,p} rooted at ver…

On the concentration of the chromatic number of random graphs

Erlang Surya, Lutz Warnke

Shamir and Spencer proved in the 1980s that the chromatic number of the binomial random graph G(n,p) is concentrated in an interval of length at most ω\sqrt{n}, and in the 1990s Al…

On the concentration of the chromatic number of random graphs

Alex Scott

Let 0<p<1 be fixed. Shamir and Spencer proved in the 1980s that the chromatic number of a random graph in G(n,p) is concentrated in an interval of length about n^{1/2}. In this exp…
