Definition A graph $G = (V(G), E(G))$ is said to be Bipartite if and only if there exists a partition $V(G) = A \cup B$ and $A \cap B = \emptyset$ Hence all edges share a vertex from both set $A$ and $B$ , and there are no edges formed between two vertices in the set $A$ , and there are not edges formed between the two vertices in $B$ The concentrations of N 2 O 5 as a function of time are listed in the following table, together with the natural logarithms and reciprocal N 2 O 5 concentrations Plot a graph of the concentration versus t, ln concentration versus t, and 1/concentration versus t and then determine the rate law and calculate the rate constantMarkov chain whose states are graphs on V This Markov chain is a model of the evolution of a random graph (rg) with vertex set V The evolution of random graphs was first studied by Erdös and Rényi 57 They investigated the least values of t for which certain properties are likely to

Figure 123 1 depicts this situation, with one line sloping down and the other up Figure 123 1 Predator–prey interactions with corresponding equations The graph on the left describes the prey, because its numbers N1 are reduced when the numbers of predator, N2, increase Likewise, the graph on the right describes the predator, becauseSuppose the edges of a complete graph on 6 vertices are coloured red and blue Pick a vertex, vThere are 5 edges incident to v and so (by the pigeonhole principle) at least 3 of them must be the same colour Without loss of generality we can assume at least 3 of these edges, connecting the vertex, v, to vertices, r, s and t, are blue(If not, exchange red and blue in what follows)Property of graphs that is used frequently in graph theory is the degree of each vertex The degree of a vertex in G is the number of vertices adjacent to it, or, equivalently, the number of edges incident on it We represent the degree of a vertex by deg(v) = r, where r is the number of vertices adjacent to v Two easy theorems to prove about

Rected graph A directed graph G = (V,E,r) is a theoretical construct created by n = Vvertices, m = Eedges and has a starting vertex r ∈V Each edge (v,u) ∈V connects two vertices v and u in one direction, which makes it possible to go from vertex v to vertex u through this edge A vertex v is dominated by another vertex w, if everyProof Among all simple graphs with vertexset V = fv 1;v 2;;v ngand deg(v i) = d i i = 1;2;;n let G be a graph for which the number r = jN G(v 1) \fv 2;;v d11gj is maximum If r = d 1, then the conclusion follows Alternatively, if r < d 1, then there is a vertex v s 2 s d 1 1 such that v 1 is not adjacent to v s, and 9vertex v t t > d 1 1 such that v If one only needs to show the distance between two languages (nodes N=2) then one could do this wonderfully in a 1D graph (dimension D=1) Just a connection line (R=1) would be enough between to languages (N=2) L1 Speakers according to Languages of Europe with Spanish (Castilian) and Italian
Rfree, and the total number of edges in this graph is n r 2 r 2 = n2 2 1 1 r The proof below compares an arbitrary K r1free graph with a suitable complete rpartite graph Proof We will prove by induction on r that all K r1free graphs with the largest number of edges are complete rpartite graphs This will imply the resultPlanar Graph A graph is said to be planar if it can be drawn in a plane so that no edge cross Example The graph shown in fig is planar graph Region of a Graph Consider a planar graph G=(V,E)A region is defined to be an area of the plane that is bounded by edges and cannot be further subdivided A planar graph divides the plans into one or more regions A classical result by Hajnal and Szemerédi from 1970 determines the minimal degree conditions necessary to guarantee for a graph to contain a K rfactorNamely, any graph on n vertices, with minimum degree δ (G) ≥ (1 − 1 r) n and r dividing n has a K rfactorThis result is tight but the extremal examples are unique in that they all have a large independent set which is the

A graph G = (V;E) is called bipartite if there is a partition of V into two disjoint subsets V = LR, such every edge e 2E joins some vertex in L to some vertex in R When the bipartition V = L R is speci ed, we sometimes denote this bipartite graph as G = (L;R;E) Theorem 2 G = (V;E) is bipartite if and only if G has no cycles of odd lengthIn this tutorial we made a line graph with error bars comparing two sets of group data in SigmaPlot from a set of raw data with replicates ©16 James ClarkBipartite graph •V can be partitioned into 2 sets V 1 and V 2 such that (u,v)∈E implies –either u ∈V 1 and v ∈V 2 –OR v∈V 1 and u∈V 2 Complete Graph •Every pair of vertices are adjacent •Has n(n1)/2 edges Complete Bipartite Graph •Bipartite Variation of Complete Graph •Every node of one set is connected to every other node on the other set Stars
N 2 Complete graphs correspond to cliques for n 3, the cycle CFor loop runs n times – when we consider node u, there are n incident edges (u, v), Generally, \(R\) is useful for picking up on the linear relationship between variables, MSE/RMSE are useful for quantifying regression performance and \(R^2\) is a convenient rescaling of MSE that is unit invariant And remember, when somebody quotes an \(R^2\) number for you, make sure to ask whether it's \(R^2\) or the square of \(R\)
