WebA DiGraph stores nodes and edges with optional data, or attributes. DiGraphs hold directed edges. Self loops are allowed but multiple (parallel) edges are not. Nodes can be arbitrary (hashable) Python objects with optional key/value attributes. By convention None is … Webmaintaining a list of "found" digraphs, and; generating all possible adjacency matrices, and for each one checking if it's isomorphic to a digraph on the list; it if isn't add it to the list, and if it's not discard this digraph. This would be quite an inefficient generation method, but would be fast enough for $4$-node digraphs. huntsville alabama botanical garden
