Recently, Ben Ming reviewed Graph Theory and found that he had forgotten it, so he planned to write such a learning note to review it.
1. Representation of Graphs
1. Adjacency Matrix
Edges are stored in a two-dimensional array with \(map[i][j]=k\) representing the point\(i\) to point\(j\) weighting \(k\).Edge-adding and edge-checking complexity ...
