WebList of Edges. A list of edges is probably the simplest way to represent a graph, but since it lacks a proper structure, it is often used just for illustrative purposes.We'll use it to explain some graph algorithms because it provides little to no overhead and allows us to focus on the algorithm implementation, rather than the implementation of the graph itself. WebTrue or false: For graphs with negative weights, one workaround to be able to use Dijkstra’s algorithm (instead of Bellman-Ford) would be to simply make all edge weights positive; for example, if the most negative weight in a graph is -8, then we can simply add +8 to all weights, compute the shortest path, then decrease all weights by -8 to return to the … greenall family
