Question 8Which of the following are true of breadth-first search? Select all that apply.Breadth-first search is implememted useing a queuebreadth
Solution
The question seems to be incomplete. However, I can provide information on the part of the question that is given.
"Breadth-first search is implemented using a queue" - This statement is true.
Breadth-first search (BFS) is a graph traversal algorithm that explores all the vertices of a graph in breadth-first order, i.e., it explores all the vertices at the present "depth" before going to the next level of depth. It uses a queue data structure. The algorithm starts from a source node and visits its adjacent nodes first before going to the next level nodes. It uses a queue to remember to visit the next node and to keep track of the nodes to be explored at each level.

When is breadth first search is optimal?
The following six questions are about breadth first search and depth first search algorithms on a given graph. Consider an undirected graph 𝐺=(𝑉,𝐸)𝐺=(𝑉,𝐸) given below, where the set of vertices 𝑉={1, 2, 3, 4, 5}𝑉={1, 2, 3, 4, 5} and the set of edges 𝐸={(1, 2),(1, 3),(1, 4),(3, 2),(3, 5)}𝐸={(1, 2),(1, 3),(1, 4),(3, 2),(3, 5)}. We run BFS and DFS algorithms on this graph starting from the vertex 1 which is the initial vertex. Answer the following questions. 1 pointWhich are the three vertices that will be added to the BFS queue in the first step of the BFS algorithm? Does the order in which they are added matter? The three vertices will be 2, 3 and 4, their order will be exactly the same as the one given in this answer option. The three vertices will be 2, 3 and 4, their order does not matter. The three vertices will be 2, 3 and 5, their order will be exactly the same as the one given in this answer option. The three vertices will be 2, 3 and 5, their order does not matter.
