  • C(u) ≠ C(v). The adjacent-vertex-distinguishing-total-chromatic number χat(G) of a graph G is the fewest colors needed in an AVD-total-coloring of G. The following lower bound for the AVD-total chromatic number can be obtained from the definition of AVD-total-coloring: If a simple graph G has two adjacent vertices of maximum degree, then χat(G) ≥ Δ(G) + 2. (wikipedia.org)
  • Otherwise, if a simple graph G does not have two adjacent vertices of maximum degree, then χat(G) ≥ Δ(G) + 1. (wikipedia.org)
  • This motivates the formulation of the minimum-adjacency vertex coloring problem which, given an interference graph G representing the potential interference between the antennas and a set of prespecified colors/channels, asks for a vertex coloring of G minimizing the number of edges receiving adjacent colors.

  • Let's say you have the following as your array of 3d position data: { {1, 1, 1}, {0, 0, 0}, {0, 0, 1} } If you simply use this as a stream as is, OpenGL will receive and process these three vertices in order (left-to-right). (khronos.org)
  • There are many ways for OpenGL to interpret a stream of, for example, 12 vertices. (khronos.org)
  • The indices control what order the vertices are received in, and indices can specify the same array element more than once. (khronos.org)
  • However, you can also specify a list of indices that will select which vertices to use and in which order. (khronos.org)
