- Implementation: Each
**edge**of a graph has an associated numerical value, called a weight. Usually, the**edge**weights are nonnegative integers. Weighted graphs may be either directed or undirected. The weight of an**edge**is often referred to as the "cost" of the**edge**. Will**create**an**Edge**class to put weight on each <b>**edge**</b>. - Mar 01, 2018 ·
**Adjacency****Matrix**is 2-Dimensional Array which has the size VxV, where V are the number of vertices in the graph. See the example below, the**Adjacency****matrix**for the graph shown above. adjMaxtrix [i] [j] = 1 when there is**edge**between Vertex i and Vertex j, else 0. It’s easy to implement because removing and adding an**edge**takes only O (1) time. - An
**adjacency****list**is a**list**or array where index represents a vertex and value represents a**list**of that vertex's adjacents. In**Java**, an**adjacency****list**can be represented by. int [] [] graph = { {1, 2}, {0, 2}, {0, 1, 3}, {2} }; An**adjacency****matrix**is a 2D array of 0s and 1s indicating the connection between two vertices in which the rows. In ... - So iterate over the Set and
**add**the nodes with an incrementing index to the map. In the last step you actually**build**the**adjacency matrix**. Iterate again over the**edge list**.Get the two node names, do a look up in the Map to get the index of the nodes and write in the**matrix**at that position. I hope the explanation makes some kind of sense..
