An edge coloring with k colors is called a k-edge-coloring and is equivalent to the problem of partitioning the edge set into k matchings. The smallest number of colors needed for an edge coloring of a graph G is the chromatic index, or edge chromatic number, χ ′ (G). A Tait coloring is a 3-edge coloring of a cubic graph.
For a graph G, let χ(G) denote the chromatic number and Δ(G) the maximum degree of G.The list coloring number ch(G) satisfies the following properties.. ch(G) ≥ χ(G).A k-list-colorable graph must in particular have a list coloring when every vertex is assigned the same list of k colors, which corresponds to a usual k-coloring.

Gantt chart: Gantt chart: color; time (flow) Type of bar chart that illustrates a project schedule; Modern Gantt charts also show the dependency relationships between activities and current schedule status. For example, used in project planning; Heat map: Heat map: color; categorical variable; Represents the magnitude of a phenomenon as color ...
The above shows that in terms of the number of vertices, the upper bound () is the best possible in general. In fact, a rainbow coloring using colors can be constructed by coloring the edges of a spanning tree of in distinct colors. The remaining uncolored edges are colored arbitrarily, without introducing new colors.
In the study of graph coloring problems in mathematics and computer science, a greedy coloring or sequential coloring [1] is a coloring of the vertices of a graph formed by a greedy algorithm that considers the vertices of the graph in sequence and assigns each vertex its first available color. Greedy colorings can be found in linear time, but ...
If you have an old browser, you will see images instead. You can learn how to use it and write help pages for your wiki. You can use the Vega v2 edit tool to make charts and copy the code to your wiki. Note that only Vega 2 is supported at the moment. Charts and maps use complex code, and you should put them into templates.
When modelling relations between two different classes of objects, bipartite graphs very often arise naturally. For instance, a graph of football players and clubs, with an edge between a player and a club if the player has played for that club, is a natural example of an affiliation network, a type of bipartite graph used in social network analysis.
