VertexDelete

VertexDelete[g,v]

makes a graph by deleting the vertex ν and all edges connected to v from the graph g.

VertexDelete[g,{v1,v2,…}]

deletes a collection of vertices from g.

VertexDelete[g,patt]

deletes all vertices that match the pattern patt.

VertexDelete[{vw,…},…]

uses rules vw to specify the graph g.

Details and Options

  • VertexDelete is also known as vertex removal.
  • VertexDelete[g,v] will delete the vertex v only if it is present in g.
  • VertexDelete works with undirected graphs, directed graphs, multigraphs, and mixed graphs.
