Algorithm improvement for enumerating binary trees

WebThe algorithm essentially picks a vertex in the graph to be deleted using a canonical labeling of the graph and tests if this was the vertex that was added. A canonical labeling can be found by McKay's nauty library. In your binary tree example, you would add a leaf somewhere in the tree.
