graph.connectToExt: Connect a node to its unvisited "extended" neighbors

Description

Connect a node to its unvisited "extended" neighbors

Usage

graph.connectToExt(adj_mat, startNode, visitedNodes)

Arguments

adj_mat

- The adjacency matrix that encodes the edge weights for the network.

startNode

- The node most recently visited by the network walker, from which p1 gets dispersed.

visitedNodes

- The history of previous draws in the node ranking sequence.

Value

adj_matAfter - The adjacency matrix where the startNode is now connected to its unvisited "extended" neighbors. An extended neighbor is the neighbor of a neighbor.

Examples

Run this code
# NOT RUN {
adj_mat = rbind(c(0,2,1,0,0,0,0), # A
                c(2,0,1,0,0,0,0), # B
