CS6515 Exam 2 Questions and answers If graph G has more than |V | − 1 edges, and there is a unique heaviest edge, then this edge cannot be part of a minimum spanning tree - ANSWER-False, because the unique heaviest edge may not be part of a cycle If G has a cycle with a unique heaviest edge e, then e cannot be part of any MST. - ANSWER-True, if the unique heaviest edge is part of a cycle then it will be removed first. Let e be any edge of minimum weight in G. Then e must be part of some...

DFS outputs - ANSWER-pre array, post array, ccnum array, prev array BFS outputs - ANSWER-dist array, prev array Explore outputs - ANSWER-visited array. When to use Dijkstra's? - ANSWER-Works for both directed and undirected graphs. Must have only non-negative edge weights. Dijkstra's outputs - ANSWER-dist array, prev array Dijkstra's runtime? - ANSWER-O((n+m) log n) log n is from using the min heap (to get the lowest cost weight) When to use Bellman Ford? - ANSWER-Use when there is a ...

Jane wants to travel from home to the local town. Jane can do this by train, by bus or by both train and bus. (a) Give an example of a problem that Jane could be answering that would give a construction problem. [1] A website gives Jane all the possible buses and trains that she could use. Jane finds 7 possible ways to make the journey. • 2 of the 7 journeys involve travelling by train for at least part of the journey • 6 of the 7 journeys involve travelling by bus for at least part o...

Binary Search Tree Correct Answer A O(log(n)) algorithm to search a binary tree for a particular item by traversing the tree in the right direction until the item is found. Binary Search Correct Answer A O(log(n)) algorithm to search a sorted list for a particular item by repeatedly halving the sublist which could contain the item. Breadth-First Traversal Correct Answer A method of traversing a graph by using a queue to visit all the neighbours of the current node before doing the same to ...

(T/F)Convergence is the time it takes for routers to arrive at a consistent understanding of the internetwork topology after a change takes place. True (T/F)A link-state routing protocol maintains and transmits a routing table that lists known networks and the distance to each network. False Static routing is recommended in the following conditions except to reduce administrative workload (T/F)When selecting routing protocols for a customer, it is important to realize that the same routing...
