AG Percus, G Istrate, B Gonçalves, RZ Sumi… - Journal of …, 2008 - pubs.aip.org
The mincut graph bisection problem involves partitioning the n vertices of a graph into
disjoint subsets, each containing exactly n/2 vertices, while minimizing the number of “cut” …

A spectral heuristic for bisecting random graphs

A Coja‐Oghlan - Random Structures & Algorithms, 2006 - Wiley Online Library
The minimum bisection problem is to partition the vertices of a graph into two classes of
equal size so as to minimize the number of crossing edges. Computing a minimum bisection …

The Ising antiferromagnet and max cut on random regular graphs

A Coja-Oghlan, P Loick, BF Mezei, GB Sorkin - SIAM Journal on Discrete …, 2022 - SIAM
The Ising antiferromagnet is an important statistical physics model with close connections to

Polynomial iterative algorithms for coloring and analyzing random graphs

A Braunstein, R Mulet, A Pagnani, M Weigt, R Zecchina - Physical Review E, 2003 - APS
We study the graph coloring problem over random graphs of finite average connectivity c.
Given a number q of available colors, we find that graphs with low connectivity admit almost …

Random geometric graphs

J Dall, M Christensen - Physical review E, 2002 - APS
We analyze graphs in which each vertex is assigned random coordinates in a geometric
space of arbitrary dimensionality and only edges between adjacent points are present. The …

Introduction to graphs

AK Hartmann, M Weigt - arXiv preprint cond-mat/0602129, 2006 - arxiv.org
Graph theory provides fundamental concepts for many fields of science like statistical

Typical solution time for a vertex-covering algorithm on finite-connectivity random graphs

M Weigt, AK Hartmann - Physical Review Letters, 2001 - APS
We analytically describe the typical solution time needed by a backtracking algorithm to
solve the vertex-cover problem on finite-connectivity random graphs. We find two different …

The cut metric, random graphs, and branching processes

B Bollobás, S Janson, O Riordan - Journal of statistical physics, 2010 - Springer
In this paper we study the component structure of random graphs with independence
between the edges. Under mild assumptions, we determine whether there is a giant …

The Metropolis algorithm for graph bisection

M Jerrum, GB Sorkin - Discrete Applied Mathematics, 1998 - Elsevier
We resolve in the affirmative a question of Boppana and Bui: whether simulated annealing
can, with high probability and in polynomial time, find the optimal bisection of a random …
