It is known that every planar graph can be colored with four colors, where no two adjacent vertices have the same color. Is it true that every nonplanar graph requires more than 4 colors? If so, explain why. If not, give an example of a nonplanar graph that can be colored with no more than 4 colors.

(2) Recall the following fact: In any planar graph, there exists a vertex whose degree is s 5 Use this fact to prove the six-color theorem: for any planar graph there exists a coloring with six colors, i.e. an assignment of six given colors (e.g. red, orange, yellow, green, blue, purple) to the vertices such that any two vertices connected by an edge have different colors. (Hint: use induction, and in the inductive step remove some verter and all edges...

Let G = (V, E) be a graph. We say that a subset S of the vertices V is an independent set if there is no edge in G joining two vertices in S. For example, given a proper colouring of the vertices of G, each colour class (i.e. the set of vertices that have some fixed colour) forms an independent set,...

Theorem 1.12) A nontrivial graph G is a
bipartite graph if and only if G contains no odd cycles.

JAVA MASTERMIND The computer will randomly select a four-character mastercode. Each character represents the first letter of a color from the valid color set. Our valid color choices will be: (R)ed, (G)reen, (B)lue and (Y)ellow. Any four-character combination from the valid color set could become the mastercode. For example, a valid mastercode might be: RGBB or YYYR. The game begins with the computer randomly selecting a mastercode. The user is then given up to 6 tries to guess the mastercode....

Definition: Given a Graph \(\mathrm{G}=(\mathrm{V}, \mathrm{E})\), define the complement graph of \(\mathrm{G}, \overline{\boldsymbol{G}}\), to be \(\bar{G}=(\mathrm{V}, E)\) where \(E\) is the complement set of edges. That is \((\mathrm{v}, \mathrm{w})\) is in \(E\) if and only if \((\mathrm{v}, \mathrm{w}) \notin \mathrm{E}\) Theorem: Given \(\mathrm{G}\), the complement graph of \(\mathrm{G}, \bar{G}\) can be constructed in polynomial time. Proof: To construct \(G\), construct a copy of \(\mathrm{V}\) (linear time) and then construct \(E\) by a) constructing all possible edges of between vertices in...
