WebMar 29, 2024 · Adjacency Matrix: Adjacency Matrix is a 2D array of size V x V where V is the number of vertices in a graph. Let the 2D array be adj[][], a slot adj[i][j] = 1 indicates that there is an edge from vertex i to vertex j. Adjacency matrix for undirected graph is always symmetric. Adjacency Matrix is also used to represent weighted graphs. WebFeb 22, 2024 · February 22, 2024. The RDKit’s conformer generator allows you to provide distance “constraints” to bias the conformers which it produces. Last week I wondered how those constraints interact with the terms which the ETKDG algorithm adds to the “distance geometry force field”. This post uses a simple example to explore that interaction.
