This argument takes a function and filters the output by testing against this property. If this property is preserved under vertex deletion, then using augment='vertices' will give you all graphs satisfying the property. Similarly for edges. If the property is not preserved as described, then you may be missing some. Also, if you use augment="edges" you get graphs on exactly N vertices, and if you use augment="vertices" you get graphs on ≤ N vertices. For any particular family of graphs it is likely there are faster ways to do it - for example we have a method of generating iso-classes of trees in constant time per tree. This is meant to be a useful general-purpose generator. -- Robert L. Miller http://www.rlmiller.org/ -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
