countGraphs -- counts the number of graphs in the list with given properties

Synopsis

• Usage:

  n = countGraphs(L, s)

  n = countGraphs(L, h)

  n = countGraphs(L, l)

• Inputs:
  • L, a list, containing graphs (mixed formats are allowed)
  • s, a string, a filter, as generated by buildGraphFilter
  • h, a hash table, a filter, as used by buildGraphFilter
  • l, a list, a filter, as used by buildGraphFilter
• Outputs:
  • n, an integer, the number of graphs in $L$ satisfying the filter

Description

i1 : L = generateGraphs 5;

i2 : countGraphs(L, {"Connectivity" => 0, "NegateConnectivity" => true})

o2 = 21
