Why is the time complexity of both DFS and BFS O( V + E )
...
DFS(analysis):
Setting/getting a vertex/edge label takes O(1) time
Each vertex is labeled twice
once as UNEXPLORED
once as VISITED
Each edge is labeled twice

Method incidentEdges is called once for each vertex

How to split/partition a dataset into training and test datasets for, e.g., cross validation?
...instructions:
from sklearn.model_selection import train_test_split
data, labels = np.arange(10).reshape((5, 2)), range(5)
data_train, data_test, labels_train, labels_test = train_test_split(data, labels, test_size=0.20, random_state=42)
This way you can keep in sync the labels for the data you'...
