EdgeWeight

EdgeWeight

is an option and annotation for Graph and related functions that specifies an edge weight.

Details

  • The following option settings can be used:
  • Automaticautomatically determine edge weights
    {vivj->wij,…}edge has weight etc.
    {w1,w2,…}give all edge weights in the same order as used by EdgeList
    {patternw,…}edge that matches the pattern has weight w
  • The wrapper Annotation[vivj,EdgeWeight->w] can be used when creating graphs in functions such as Graph etc.
  • The weight can be any expression.
  • The weight can be interpreted as cost or capacity, or can have other special meanings for different graph computation functions.
