Graph Theory Coloring Number
This video discusses the concept of graph coloring as well as the chromatic number.
Graph theory coloring number. The minimum number of colors required for vertex coloring of graph g is called as the chromatic number of g denoted by x g. If g is not a null graph then χ g 2. If is odd then the last vertex would have the same color as the first vertex so the chromatic number will be 3. Chromatic number of a graph is the minimum number of colors required to properly color the graph.
Graph coloring in graph theory graph coloring is a process of assigning colors to the vertices such that no two adjacent vertices get the same color. A graph coloring for a graph with 6 vertices. It is impossible to color the graph with 2 colors so the graph has chromatic number 3. This is called a vertex coloring.
It is an assignment of labels traditionally called colors to elements of a graph subject to certain constraints. You can also connect with us at. A graph coloring is an assignment of labels called colors to the vertices of a graph such that no two adjacent vertices share the same color. Graph coloring chromatic number with solved examples graph theory classes in hindi graph theory video lectures in hindi for b tech m tech mca students.
Solution if the vertex are colored in an alternating fashion the cycle graph requires 2 colors. In its simplest form it is a way of coloring the vertices of a graph such that no two adjacent vertices are of the same color.
