Watts and Strogatz [Nature (London) 393, 440 (1998)] have recently introduced a model for disordered networks and reported that, even for very small values of the disorder $p$ in the links, the network behaves as a ``small world.'' Here, we test the hypothesis that the appearance of small-world behavior is not a phase transition but a crossover phenomenon which depends both on the network size $n$ and on the degree of disorder $p$. We propose that the average distance $\ensuremath{\ell… Expand
On the properties of small-world network models
Abstract:We study the small-world networks recently introduced by Watts and Strogatz [Nature 393, 440 (1998)], using analytical as well as numerical tools. We characterize the geometrical propertiesExpand
Infinite characteristic length on small-world systems
It was recently claimed that on d-dimensional small-world networks with a density p of shortcuts, the typical separation s(p) ~ p^{-1/d} between shortcut-ends is a characteristic length forExpand

TLDR
There is one nontrivial length-scale in the small-world network model of Watts and Strogatz, analogous to the correlation length in other systems, which is well-defined in the limit of infinite system size and which diverges continuously as the randomness in the network tends to zero, giving a normal critical point in this limit.

On the Evolution of Finite-Sized Complex Networks with Constrained Link Addition
TLDR
In finite-sized complex networks edge growth can result in transitional scale-free networks, as well as regular network, finitesized complex network, with average path optimal edge growth. Expand
Optimal paths in disordered complex networks.
TLDR
For strong disorder, where the maximal weight along the path dominates the sum, l(opt) approximately N(1/3) in both Erdos-Rényi (ER) and Watts-Strogatz (WS) networks. Expand
Spectra of "real-world" graphs: beyond the semicircle law.
TLDR
Methods to determine the eigenvalues of networks comparable in size to real systems are developed, obtaining several surprising results on the spectra of adjacency matrices corresponding to models of real-world graphs. Expand
Information Dynamics in Small-World Boolean Networks
TLDR
An ensemble investigation of the computational capabilities of small-world networks as compared to ordered and random topologies finds that the ordered phase of the dynamics and topologies with low randomness are dominated by information storage, while the chaotic phase is dominated byInformation storage and information transfer.

Structural properties of scale‐free networks
Many networks have been reported recently to follow a scalefre degree distribution in which the fraction of sites having k connections follows a power law: P (k) = k . In this chapter we study theExpand
Physical realizability of small-world networks.
TLDR
For such systems the emergence and physical realizability of small-world topology is discussed, and a simple argument allows us to understand under which condition and at what expense a small world results. Expand
