regardless of the edge direction

called its level, where, for each directed edge (a b) the

where the nodes are keys and the levels are values, or an association
list of nodes and their levels, along with the number of levels in
DIGRAPH.
Return the maximum flow from FROM and to TO in GRAPH.
GRAPHS must be a network with numeric values of all edges (otherwise a
default cost of 1 is used for every edge). The Ford-Fulkerson
algorithm is used. Optional argument HEURISTIC if supplied is passed
through to guide the A* search used in ‘shortest-path’.
Combine EDGE1 and EDGE2 in GRAPH into a new EDGE.
Optionally provide a value for the new edge, the values of EDGE1 and

Return a list of the receivers in digraph.
Return the residual graph of GRAPH with FLOW.
Each edge in the residual has a value equal to the original capacity
minus the current flow, or equal to the negative of the current flow.
Return a copy of GRAPH with all edges reversed.
Return the shortest path in GRAPH from A to B.
Implemented using A* search. Optional argument HEURISTIC may be a
function which returns an estimated heuristic cost from an node to the
target B. The default value for HEURISTIC is the constant function of
0, reducing this implementation to Dijkstra’s algorithm. The
HEURISTIC function must satisfy HEURITIC(x)≤d(x,y)+HEURITIC(y) ∀ x,y
in GRAPH allowing the more efficient monotonic or "consistent"
implementation of A*.
Return the nodes of GRAPH partitioned into strongly connected components. Uses Tarjan’s algorithm.
Return the subgraph of GRAPH restricted to NODES.
