Talk:Barabási–Albert model

page should be moved to Barabási-Albert model

To keep it more easily findable like the and keep the naming consistency, i.e. Erdős-Rényi model.

Picture

Can someone please upload an image of a (verified!) BA model graph with about 50-100 Vertices? I am implementing one at the moment, and find it very difficult to verify if it's correct. I think in this dimension, a human can see at first glance, if it's the same type of graph or other. --80.136.123.234 15:04, 18 October 2007 (UTC)

Description of the Algorithm

The Algorithm is unsufficiently described: It's not clear whether m is constant throughout the complete algorithm. Also there is no hint, should the p_i be updated each time a connection is added, or only after adding a node with all its m connections? —Preceding unsigned comment added by 192.35.241.121 (talk) 19:27, 17 February 2008 (UTC)

Almost every paper I can find on the topic uses a fixed m throughout the process, the most common being m = 2.

and what the heck is j? —Preceding unsigned comment added by 203.122.247.105 (talk) 11:54, 8 August 2009 (UTC)

Value of m0 in caption of figure

The example BA network has a caption claiming m0=1. Wouldn't that imply no edges and k_0=0 resulting in P(k_0) = 0? That would mean no edges ever get added. The algorithm as described seems only well defined for m0 > 1. — Preceding unsigned comment added by 73.110.38.161 (talk) 21:15, 14 July 2018 (UTC)

Little bit confused on the parameterization of this model

Compare this page to the https://en.wikipedia.org/wiki/Watts%E2%80%93Strogatz_model, it's not clear what parameterization this model has. In other words, what are the inputs to a graph generator based on the BA model? BAModel(number_nodes, ??, ??, ...). — Preceding unsigned comment added by Orangesherbet0 (talk • contribs) 22:44, 14 February 2020 (UTC)
