Description
The number of maximal spanning forests contained in a graph.
A maximal spanning forest in a graph is a maximal acyclic subgraph. In other words, a spanning forest is a union of spanning trees in all connected components. See also [1] for this and further definitions.
For connected graphs, this is the same as [[St000096]].

This is ∑{u,v}∈E|d(u)−d(v)|, where E is the set of edges and dv is the degree of vertex v, see [1].

The Padmakar-Ivan index of a graph.
For an edge e=(u,v), let ne,u be the number of edges in a graph G induced by the set of vertices {w:d(u,w)<d(v,w)}, where d(u,v) denotes the distance between u and v.
Then the PI-index of G is

Description
The length of a longest path in a graph such that after removing the paths edges, every vertex of the path has distance two from some other vertex of the path.
Put differently, for every vertex v of such a path P, there is a vertex w∈P and a vertex u∉P such that (v,u) and (u,w) are edges.
The length of such a path is 0 if the graph is a forest.
It is maximal, if and only if the graph is obtained from a graph H with a Hamiltonian path by joining a new vertex to each of the vertices of H.
