DESCRIPTION

Builds a random (binary tree-child) phylogenetic network each time next_network is called.

new

 Title   : new
 Usage   : my $factory = new Bio::PhyloNetwork::RandomFactory();
 Function: Creates a new Bio::PhyloNetwork::RandomFactory
 Returns : Bio::PhyloNetwork::RandomFactory
 Args    : -numleaves => integer
            OR
           -leaves => reference to an array (of leaves names)
           -numhybrids => integer [optional]
           -norepeat => boolean [optional]

Returns a Bio::PhyloNetwork::RandomFactory object. Such an object will create random binary tree-child phylogenetic networks each time next_network is called.

If the parameter -leaves=>\@leaves is given, then the set of leaves of these networks will be @leaves. If it is given the parameter -numleaves=>$numleaves, then the set of leaves will be ``l1''...``l$numleaves''.

If the parameter -numhybrids=>$numhybrids is given, then the generated networks will have exactly $numhybrids hybrid nodes. Note that, necessarily, $numhybrids < $numleaves. Otherwise, the number of hybrid nodes will be chosen at random for each call of next_network.

If the parameter -norepeat=>1 is given, then successive calls of next_network will give non-isomorphic networks.

next_network

 Title   : next_network
 Usage   : my $net=$factory->next_network()
 Function: returns a random network
 Returns : Bio::PhyloNetwork
 Args    : none
