eulerian orientation造句

Eulerian orientations and well-balanced orientations provide important special cases of strong orientations; in turn, strong orientations may be generalized to totally cyclic orientations of disconnected graphs.
"' Lieb's square ice constant "'is a mathematical constant used in the field of combinatorics to quantify the number of Eulerian orientations of grid graphs.
Nash-Williams'orientations also have the property that they are as close as possible to being Eulerian orientations : at each vertex, the indegree and the outdegree are within one of each other.
If " G " is a planar graph, then 2 T _ G ( 3, 3 ) equals the sum over weighted Eulerian orientations in a medial graph of " G ", where the weight of an orientation is 2 to the number of saddle vertices of the orientation ( that is, the number of vertices with incident edges cyclicly ordered " in, out, in out " ).
