n = countGraphs(L, s)
n = countGraphs(L, h)
n = countGraphs(L, l)
Counts the number of graphs in a list that satisfy certain restraints as given in the filter (see buildGraphFilter). Notice that the input list can be graphs represented as instances of the class Graph or in a nautybased String format.
For example, we can count the number of connected graphs on five vertices.


The object countGraphs is a method function.
