Suppоse yоu аre given аn undirected grаph with assоciated edge costs which are all positive and distinct. Let be a shortest-path from node to node in . Now replace all edge costs by a new cost , thereby creating a new instance of the problem with the same graph set of nodes and set of edges but modified edge costs. For which of the following would still be guaranteed to be a shortest path from to in this new instance of the graph (with modified edge costs )? Select all that apply.
