Prove that if the breadth-first search algorithm visits node u before node v, then u.d ≤ v.d. Give a simple direct proof. Use induction on when v is visited. More precisely, prove, for every i ≥ 1, that if v is the ith node visited and u is visited before v, then u.d ≤ v.d.

(5 marks) a. The pseudo-code for breadth-first search, modified slightly from Drozdek,1 is as follows: void breadthFirstSearch (vertex w) for all vertices u num (u) 0 null edges i=1; num (w) i++ enqueue (w) while queue is not empty dequeue ( V= for all vertices u adjacent to v if num(u) is 0 num (u) = i++; enqueue (u) attach edge (vu) to edges; output edges; Now consider the following graph. Give the breadth-first traversal of the graph, starting from...

Consider the width search algorithm from a start node s. The diameter of an undirected, contiguous Graph G = (V, E) is defined as the maximum over all node pairs v, w ∈ V of the length of the shortest path from v to w. We assume that each edge has the length of 1. Specify an extension of the width search algorithm in pseudo code that has the diameter of an undirected graph G = (V, E). First explain...
