WebThe nearest neighbor graph (NNG) analysis is a widely used data clustering method [1]. A NNG is a directed graph defined for a set E of points in metric space. Each point of this set is a vertex of the graph. The directed edge from point A to point B is drawn for point B of the set whose distance from point A is minimal. WebIn BFS, we initially set the distance and predecessor of each vertex to the special value ( null ). We start the search at the source and assign it a distance of 0. Then we visit all the neighbors of the source and give each neighbor a distance of 1 and set its predecessor to be the source. Then we visit all the neighbors of the vertices whose ... how do i remove the black background
