A bridge is an edge of a graph whose deletion increases its number of connected components....
6. Prove that the following graphs are connected: (a) The 3 vertex cycle: (b) The following 4 vertex graph: (c) K 7. An edge e of a connected graph G is called a cut edge if the graph G obtained by deleting that edge (V(G) V(G) and E(G) E(G) \<ej) is not connected. Prove that if G1 and G2 are connected simple graphs which are isomorphic and if G1 has a cut edge, then G2 also has a cut edge....
3. Graph Connected Components (25 pts) You are given an undirected, unweighted graph that may be disconnected i.e. some vertices may not be reachable from other vertices. Every group of mutually reachable vertices forms an island, called a con- nected component. There is no path between vertices in different connected components. If a graph is not disconnected, then its vertices are in a single connected component, which is the entire graph itself. Implement a method using depth-first search that will...
ignore red marks. Thanks
10. (16) You will compute the strongly connected components of this graph in three steps. a. STRONGLY-CONNECTED-COMPONENTS (G) (7) Perform a depth-first search on call DFS(G) to compute finishing times w/ for each vertex the following graph. (To make 2 compute GT this easier to grade, everyone call DFS(GT), but in the main loop of DFS, consider the vertices in order of decreasing wf (as computed in line 1) please start with vertex "a" and 4...

Question 1: Given an undirected connected graph so that every edge belongs to at least one simple cycle (a cycle is simple if be vertex appears more than once). Show that we can give a direction to every edge so that the graph will be strongly connected. Question 2: Given a graph G(V, E) a set I is an independent set if for every uv el, u #v, uv & E. A Matching is a collection of edges {ei} so...

Answer the following questions based on the graph below. 1w a. b. c. d. What are the vertices? What is the degree of vertex u? What is the degree of vertex s? What is one circuit in the graph?
Consider the figure above. The six circuits are each made of
more than two connected components. The rectangles are the
components and the lines are connecting wires. Each circuit has two
circular terminals. We consider the circuits' behaviors with
electricity going in one of the terminals and going out the other
when the terminals are connected to a battery or another
circuit.
A) Which of the six circuits have all the components in series?
(Select all the circuits that have...
