X = [ Chem.MolFromSmiles(i) for i in X] #生成邻接矩阵(当然,一个分子的特征,不单单可以考虑分子图的结构,也可以考虑节点和边的信息,为了简便起见,这里仅仅考虑结构) X = [Chem.rdmolops.GetAdjacencyMatrix(i) for i in X] #由邻接矩阵转为dgl的图(先转化为稀疏矩阵,然后构构建图) from scipy.s...
A root of a dag is a vertex r such that every vertex of the dag can be reached by a directed path from r. Write pseudocode to determine whether a dag is rooted. Consider the following algorithm to check connectivity of a graph defined by its adjac...
A digital circuit is a circuit where the signal must be high or low or we can say in boolean terms. Digital gates are commonly made from a small circuit called logic gates. Each logic gates performs a specific task. Answer and Explanation:1 1) 2)...
