Method Detail

compute

public double compute(D sg1,
                      D sg2)

Computes the edit distance between the two SimpleGraph instances with which the object was instantiated. Precondition: the algorithm only returns a useful edit distance if the graphs both have at least one 'source node' (a node with no incoming arcs.) Otherwise, Double.MAX_VALUE is returned.

Parameters:

sg1 - A graph.

sg2 - A graph.

Returns:

edit distance
