单词 random graph
释义
random graph

Mathematics
  • Given a set of vertices, a random graph may be created by independently assigning an edge between each pair of vertices with a given probability p. This leads to possible combinatorics arguments to demonstrate, amongst all such random graphs, the existence of a graph with certain properties.


Statistics
  • A graph constructed following rules governed by probability. Let j and k denote two nodes (with j=k being a possibility). With probability pjk, construct an arc between these nodes. The value of pjk might be the same for all pairs of nodes, or it might vary.

    random graph

    Random graph. The example shows a random graph that is not a connected graph, since node 5 is not connected to the other nodes.
