Nevertheless, for some graphs of specific kinds it can be solved effectively. WebThe diameter of a graph G is diam (G) = sup {d (a, b) : a and b are distinct vertices of G}. The girth of G is the length of the shortest cycle in G, denoted by gr (G) [we let gr (G) = ∞ if G has no cycles]. The graph G is complete if each pair of distinct vertices is joined by an edge. We use K n to denote the complete graph with n vertices.

WebMay 21, 2024 · The clique number is $5$. Note that there can be at most one even number in a clique, as two even numbers would have a common factor of $2$. Also note that $3$ and $9$ cannot be in the same clique as $3$ divides both. So not all odd numbers can be used. This gives us a maximum bound of $5$ numbers in a clique. WebJan 6, 2002 · We show that a claw-free graph is 2-divisible if and only if it does not contain an odd hole: we conjecture that this result is true for any graph, and present further conjectures relating 2-divisibility to the strong perfect graph conjecture. We also present related results involving the chromatic number and the stability number, with ...

WebIf you double the last digit and subtract it from the rest of the number and the answer is: 0, or divisible by 7 then the number itself is divisible by 7. Example: 672 (Double 2 is 4, 67-4=63, and 63÷7=9) Yes. 905 (Double 5 is 10, 90-10=80, and 80÷7=11 3/7) No. If the number is too big you can repeat until you find the solution.
In the mathematical area of graph theory, a clique is a subset of vertices of an undirected graph such that every two distinct vertices in the clique are adjacent. That is, a clique of a graph $${\displaystyle G}$$ is an induced subgraph of $${\displaystyle G}$$ that is complete. Cliques are one of the … See more A clique, C, in an undirected graph G = (V, E) is a subset of the vertices, C ⊆ V, such that every two distinct vertices are adjacent. This is equivalent to the condition that the induced subgraph of G induced by C is a See more Mathematical results concerning cliques include the following. • Turán's theorem gives a lower bound on the size of a clique in See more The word "clique", in its graph-theoretic usage, arose from the work of Luce & Perry (1949), who used complete subgraphs to model cliques (groups of people who all … See more • Weisstein, Eric W., "Clique", MathWorld • Weisstein, Eric W., "Clique Number", MathWorld See more In computer science, the clique problem is the computational problem of finding a maximum clique, or all cliques, in a given graph.
