In this article, the bisection width of a graph G is the minimum over all partitions of the number of "cross edges" between the parts of the graph G with edge probability c n.
Abstract
Consider partitions of the vertex set of a graph G into two sets with sizes differing by at most 1: the bisection width of G is the minimum over all such partitions of the number of ‘‘cross edges’’ between the parts. We are interested in sparse random graphs Ž . G with edge probability c n. We show that, if c ln 4, then the bisection width is n n, c n with high probability; while if c ln 4, then it is equal to 0 with high probability. There are corresponding threshold results for partitioning into any fixed number of parts. 2001 John Wiley & Sons, Inc. Random Struct. Alg., 18, 31 38, 2001

The phase transition in inhomogeneous random graphs

TL;DR: A very general model of an inhomogeneous random graph with (conditional) independence between the edges is introduced, which scales so that the number of edges is linear in thenumber of vertices.

The phase transition in inhomogeneous random graphs

TL;DR: The “classical” random graph models, in particular G(n,p), are “homogeneous,” in the sense that the degrees tend to be concentrated around a typical value.

Metrics for sparse graphs

TL;DR: This paper deals mainly with graphs with $o(n^2)$ but $\omega(n)$ edges: a companion paper [arXiv:0812.2656] will discuss the (more problematic still) case of {\em extremely sparse} graphs, with O( n) edges.

Sparse graphs: Metrics and random models

TL;DR: Bollobas, Janson and Riordan as mentioned in this paper introduced a family of random graph models producing inhomogeneous graphs with n vertices and Θ(n) edges whose distribution is characterized by a kernel, i.e., a symmetric measurable function κ: [ 0, 1]2 → [0, ∞).

Some simplified NP-complete graph problems

TL;DR: This paper shows that a number of NP - complete problems remain NP -complete even when their domains are substantially restricted, and determines essentially the lowest possible upper bounds on node degree for which the problems remainNP -complete.

Improved approximation algorithms for MAX k-CUT and MAX BISECTION

TL;DR: Polynomial-time approximation algorithms with nontrivial performance guarantees are presented for the problems of partitioning the vertices of a weighted graph intok blocks so as to maximize the weight of crossing edges.
