For directed graphs, the minimum spanning tree problem is called the Arborescence problem and can be solved in quadratic time using the Chu Liu / Edmonds algorithm.

Some authors restrict the phrase to the case where the edges are all directed towards a particular vertex, or all directed away from a particular vertex ( see arborescence ).

"Evryali " is connected to earlier works, particularly " Synapha?" ( 1969 ), certain parts of which led to the creation of the arborescence technique.
14.
It's also possible to define a useful notion by reversing all the arcs of an arborescence, i . e . making them all point to the root rather than away from it.
15.
The software starts from a primary cuboid ( i . e . including form ) and manages the related arborescence in which each cuboid is either full, either empty or subdivided in 8 cuboids.
16.
The algorithm finds in which it is the value of the bottleneck edge in any MBSA . After is found any spanning arborescence in is an MBSA in which is the graph where all its edge s costs are.

In 2016, Lionel Rogg, John's source of inspiration since his boyhood, and his friend for many years, wrote an organ piece " Arborescence " especially for him, to celebrate John's 60th birthday.

Such digraphs are also designated by a variety of terms such as "'in-tree "'or "'anti-arborescence "'etc . W . T . Tutte distinguishes between the two cases by using the phrases " arborescence diverging from " [ some root ] and " arborescence converging to " [ some root ].
