Let G = (V;E) be an undirected and unweighted graph. Let S be a subset of the vertices. The graph induced on S, denoted G[S] is a graph that has vertex set S and an edge between two vertices u, v that is an element of S provided that {u,v} is an edge of G. A subset K of V is called a killer set of G if the deletion of K kills all the edges of G, that is...

please throughly explain each step.47.21. What does it mean for two graphs to be the same? Let G and H be graphs. We say th G is isomorphic to H provided there is a bijection f VG)-V(H) such that for all a, b e V(G) we have a~b (in G) if and only if f(a)~f (b) (in H). The function f is called an isomorphism of G to H We can think of f as renaming the vertices of G...

Consider an unweighted, undirected graph G = 〈V, E). The neighbourhood of a node u E V in the graph is the set of all nodes that are adjacent (or directly connected) to v. Subsequently, we can define the neighbourhood degree of the node v as the sum of the degrees of all its neighbours (those nodes that are directly connects to v) (a) Design an algorithm that returns a list containing the neighbourhood degree for each node v V,...

This question needs to be done using pseudocode (not any
particular programming language). Thanks

What does it mean for two graphs to be the same? Let G and H be graphs. We Say that G is isomorphic to H provided there is a bijection f : V(G) rightarrow V(H) such that for all a middot b epsilon V(G) we have a~b (in G) if and only if f(a) ~ f(b) (in H). The function f is called an isomorphism of G to H. We can think of f as renaming the vertices of G...

Problem 5. (12 marks) Connectivity in undirected graphs vs. directed graphs. a. (8 marks) Prove that in any connected undirected graph G- (V, E) with VI > 2, there are at least two vertices u, u є V whose removal (along with all the edges that touch them) leaves G still connected. Propose an efficient algorithm to find two such vertices. (Hint: The algorithm should be based on the proof or the proof should be based on the algorithm.) b....
