Animation Visualization for Vertex Coloring of Polyhedral Graphs
Vertex coloring of a graph is the assignment of labels to the
vertices of the graph so that adjacent vertices have different labels.
In the case of polyhedral graphs, the chromatic number is 2, 3, or 4.
Edge coloring problem and face coloring problem can be
converted to vertex coloring problem for appropriate polyhedral
We have been developed an interactive learning system of
polyhedra, based on graph operations and simulated elasticity
potential method, mainly for educational purpose.
In this paper, we introduce a learning subsystem of vertex coloring,
edge coloring and face coloring, based on minimum spanning tree
and degenerated polyhedron, which is introduced in this paper.
