WebPath Length Figure 2 contains a graph of the average path length data verses temperature for the polymeric gel and E.R. random graphs. This is the same data as in figure 1, just a closer view. Tables 1 and 2 contain the average path length data (experimental and calculated) for the random graph and the polymeric gel. WebAlthough the diameter only tells us the length of the longest path in the random graph, that path length will actually be very common. This paper is also about the random graph where each edge is present independently with probability , but the same thing should hold for the random graph with vertices and random edges.

WebI’ve analyzed a graph consisting of 157 nodes. When i compute a matrix of weighted distances (shorthest paths) between nodes my matrix is 141×141 not 157×157 (as I understand it, this is mainly because of existing separated dyads (pairs of 2 nodes connected only to each other and disconnected from all other nodes in graph). http://cn.voidcc.com/question/p-fdkbimgz-dr.html
