NeighborhoodSubgraph
NeighborhoodSubgraph[g,i,r]
gives a subgraph consisting of vertices that can be reached from vertex i within r hops.
NeighborhoodSubgraph[g,i]
gives a subgraph consisting of vertices that can be reached from vertex i.
更多信息和选项
- NeighborhoodSubgraph functionality is now available in the built-in Wolfram Language function NeighborhoodGraph.
- To use NeighborhoodSubgraph, you first need to load the Graph Utilities Package using Needs["GraphUtilities`"].
- NeighborhoodSubgraph returns a subgraph consisting of vertices that can be reached from a given vertex within certain hops.
范例
基本范例 (2)
Needs["GraphUtilities`"]This defines a simple directed graph:
g = {1 -> 2, 2 -> 3, 1 -> 3, 2 -> 4, 4 -> 5, 5 -> 6, 6 -> 4};x = Thread[VertexList[g] -> GraphCoordinates[g]];GraphPlot[g, VertexCoordinateRules -> x, VertexLabeling -> True, DirectedEdges -> True]This finds a subgraph from vertices that can be reached from vertex 2 within 1 hop:
sg = NeighborhoodSubgraph[g, 2, 1]NeighborhoodSubgraph has been superseded by NeighborhoodGraph:
g = Graph[{1 -> 2, 2 -> 3, 1 -> 3, 2 -> 4, 4 -> 5, 5 -> 6, 6 -> 4}]EdgeList[NeighborhoodGraph[g, 2, 1, DirectedEdges -> True]]文本
