phylox.generators.randomTC.random_tc_network

phylox.generators.randomTC.random_tc_network.random_tree_child_sequence(leaves, reticulations, seed=None)

Returns a random tree-child sequence with a given number of leaves and reticulations :param leaves: number of leaves :param reticulations: number of reticulations :param seed: seed for the random number generator :return: a random tree-child sequence

Example:

>>> from phylox.generators.randomTC.random_tc_network import random_tree_child_sequence
>>> seq = random_tree_child_sequence(5, 2)
>>> len(seq)
6

phylox.generators.randomTC.random_tc_network.random_tree_child_subsequence(seq, r, seed=None)

Returns a random tree-child subsequence with a given number of reticulations :param seq: a tree-child sequence :param r: number of reticulations in the subsequence :param seed: seed for the random number generator :return: a random tree-child subsequence

Example:

>>> from phylox.generators.randomTC.random_tc_network import random_tree_child_subsequence
>>> seq = [(4,1), (4, 1), (3, 1), (2, 1), (2, 1), (2,1)]
>>> newSeq = random_tree_child_subsequence(seq, 1)
>>> len(newSeq)
4

phylox.generators.randomTC.random_tc_network.generate_network_random_tree_child_sequence(leaves, reticulations, label_leaves=True, seed=None)

Returns a random tree-child network with a given number of leaves and reticulations :param leaves: number of leaves :param reticulations: number of reticulations :param label_leaves: whether to label the leaves :return: a random tree-child network

Example:

>>> from phylox.generators.randomTC.random_tc_network import generate_network_random_tree_child_sequence
>>> network = generate_network_random_tree_child_sequence(5, 2)
>>> len(network.leaves)
5
>>> network.reticulation_number
2
