We investigate the growth of a class of networks in which a new node first picks a mediator at random and connects with m randomly chosen neighbors of the mediator at each time step. We show that the degree distribution in such a mediation-driven attachment (MDA) network exhibits power-law P(k)∼k−γ(m) with a spectrum of exponents depending on m. To appreciate the contrast between MDA and Barabasi–Albert (BA) networks, we then discuss their rank-size distribution. To quantify how long a leader… Expand
Dynamic scaling, data-collapse and self-similarity in mediation-driven attachment networks
Recently, we have shown that if the $i$th node of the Barab\'{a}si-Albert (BA) network is characterized by the generalized degree $q_i(t)=k_i(t)t_i^\beta/m$, where $k_i(t)\sim t^\beta$ and $m$ areExpand
Universality class of explosive percolation in Barabási-Albert networks
TLDR
This work study explosive percolation in Barabási-Albert network, in which nodes are born with degree k = m, for both product rule (PR) and sum rule (SR) of the Achlioptas process finds that the critical exponents ν, α, β and γ for m > 1 are found to be independent not only of the value of m but also of PR and SR.

Modelling and Analysis the Network Model Controlled by Mediation-Driven Attachment Rule
TLDR
The problem of modeling scale-free networks is considered and the dependence of the scaling factor of nodes degree distribution on the control parameter – the number of links associated with incoming nodes – is analyzed both analytically and by numerical simulation. Expand
Correlated copying in a hidden network model
We introduce the concept of a hidden network model – a generative two-layer network in which an observed network evolves according to the structure of an underlying hidden layer. We apply the conceptExpand
The longest path in the Price model
TLDR
A reverse greedy path is defined and it is shown both analytically and numerically that this scales with the logarithm of the size of the network with a coefficient given by the number of edges added using random attachment. Expand
Heterogeneous node copying from hidden network structure
Node copying is an important mechanism for network formation, yet most models assume uniform copying rules. Motivated by observations of heterogeneous triadic closure in real networks, we introduceExpand
Elastic Scale-Free Networks Model Based on the Mediaton-Driven Attachment Rule
TLDR
Applying the copy-factor as the control parameter instead of traditionally used number of incoming links makes it possible to generate networks model, which combines the key benefits of mediation- driven attachment, such as indirect using the nodes degree, and elasticity,such as different relative growth rates for links and nodes.

COVID-19 Should be Suppressed by Mixed Constraints -- from Simulations on Constrained Scale-Free Networks
TLDR
For quickly suppressing the number of infections, restrict W to less than 4 if the constraint to make m0 at most 1 is too strict, and set m0 to 4 or less works for quick reduction of infections according to the result. Expand

Infection of virus is here simulated over human networks where the widths, defined as two constants representing the size of the contacting community, are constrained. In this model, the real-spaceExpand
Scale-free Network-based Differential Evolution
TLDR

Scale-free network growth by ranking.
TLDR
A criterion of network growth that explicitly relies on the ranking of the nodes according to any prestige measure, be it topological or not is proposed, which may explain the frequency and robustness of scale-free degree distributions in real networks, as illustrated by the special case of the Web graph.

TLDR
It is found both from simulation and analytically that the network shows scaling behavior only in the region alpha<1, when alpha increases from -infinity to 0, and the exponent gamma of the distribution of connectivities grows from 2 to the value for the network without aging. Expand

A class of networks that grow by enhanced redirection is introduced, and each either attaches to a randomly chosen target node or to the parent of the target with probability r, where r is an increasing function of the degree of the parent. Expand
