Igraph small world
WebA small-world network is a mathematical graph in which most nodes are not neighbors of one another, but the neighbors of any given node are likely to be neighbors of each other. Due to this, most neighboring nodes can be reached from every other node by a small number of hops or steps. [1] WebThe Watts-Strogatz small-world model Description Generate a graph according to the Watts-Strogatz network model. Usage sample_smallworld (dim, size, nei, p, loops = FALSE, multiple = FALSE) smallworld (...) Arguments Details First a lattice is created with the given dim, size and nei arguments.
