Table 2

Q-VOTE(S, Q, p):
1.
Randomly select a quartet topology in Q as the initial phylogeny T;
2.
Delete the four taxa of T from the taxon set S;
3.
Randomly select a taxon s from S;
4.
Locate a separator v of T;
5.
Decide which sub-phylogeny of T - {v} taxon s should be inserted into based on the votes;
6.
If the located sub-phylogeny has only one edge,
6.1.
     Insert taxon s on that edge and let the new phylogeny be T;
7.
Else,
7.1.
     Merge the other two sub-phylogenies as a super taxon (which replaces v);
7.2.
     Let the located sub-phylogeny with the super taxon be the new current phylogeny T;
7.3.
     Go back to Step 4;
8.
Delete taxon s from S;
9.
If S is not empty,
9.1.
     Go back to Step 3;
10.
Else,
10.1.
     Output the phylogeny T.
