graph20 {NetworkDistance}

20 adjacency matrices from Erdős–Rényi models

Description

Simulated list of 20 adjacency matrices of 28 nodes. First 10 are from Erdős–Rényi model with p=0.9, and the latter 10 are generated using p=0.5. Each element in the list is of size (28\times 28), symmetric, having values in 0 or 1, and every diagonal element is set as 0 in accordance with no self-loop assumption.

Usage

data(graph20)

Format

A list of 20 adjacency matrices of size (28\times 28).

Details

Below is the code used to generate graph20:

require(stats)
graph20 = list()
for (i in 1:10){ # type-1 adjacency matrices
  rbin   = rbinom(784,1,0.9)
  mat    = matrix(rbin, nrow=28)
  matout = mat*t(mat)
  diag(matout) = 0
  graph20[[i]]=matout
}
for (i in 11:20){ # type-2 adjacency matrices
  rbin   = rbinom(784,1,0.5)
  mat    = matrix(rbin, nrow=28)
  matout = mat*t(mat)
  diag(matout) = 0
  graph20[[i]]=matout
}
