create_balanced_blocks {rsetse}

Create balanced blocks

Description

Separates the network into a series of bi-connected components that can be solved separately. Solving smaller subgraphs using the bi-connected component method reduces the risk of network divergence. This function is seldom called independently of setse_bicomp

Usage

create_balanced_blocks(g, force = "force", bigraph = bigraph)

Arguments

g

An igraph object. The network for which embeddings will be found

force

A character vector. The name of the node attribute that is the force exerted by the nodes

bigraph

A list. the list of biconnected components produced by the biconnected_components function. This function take a non trivial amount of time on large graphs so this pass through minimises the function being called.

Details

When networks are separated into the bi-connected subgraphs or blocks. The overall network balance needs to be maintained. create_balanced_blocks maintains the balance by summing the net force across the all the nodes that are being removed from the subgraph. Therefore a node that is an articulation point has a force value equal to the total of all the nodes on the adjacent bi-connected component.

Value

A list containing all the bi connected component where each component is balanced to have a net force of 0.

Examples

library(igraph)
#create a list of balanced network using the biconnected_network dataset
balanced_list <-create_balanced_blocks(biconnected_network, 
bigraph = biconnected_components(biconnected_network))

#count the edges in each of the bi-components
sapply(balanced_list, ecount)
