WebAdjacency matrices are very good for dense graphs, and adjacency lists are good for sparse graphs. So it depends on what your graph looks like, but it also depends on whether you care more about running time or memory. If you represent your adjacency matrix as a hash table, you can get very good lookup times without using n^2 memory. WebIn graph theory and computer science, an adjacency matrix is a square matrix used to represent a finite graph.The elements of the matrix indicate whether pairs of vertices are adjacent or not in the graph.. In the special case of a finite simple graph, the adjacency matrix is a (0,1)-matrix with zeros on its diagonal. If the graph is undirected (i.e. all of its …

That’s because atoms 1-3 are bonded only to carbon (atom 4). Also, the diagonal is always 0 because atoms cannot be bonded with themselves. " - Rdkit adjacency matrix
