Whoops, looks like Johnson's algorithm is missing from the online
documentation of the C core then. Thanks for pointing that out!
Anyways, the time complexity of Johnson's algorithm is O(s |V| log|V| +
|V| |E|), where s is the number of source vertices, |V| and |E| are the
number of vertices and edges.
