Hallo, as an alternative, I recommend that the Schulze proportional ranking method should be used and that the first S candidates (where S is the number of seats) should be elected. For example A90, the runtime to calculate the first S=12 candidates is below 0.1 s. This recommendation also has the advantage that it is house-monotonic. Only in 3 of the 66 examples in Tideman's database, Schulze STV and Schulze proportional ranking lead to different results: * In example A10, Schulze STV chooses MNP. The first S=3 candidates of Schulze proportional ranking are AMP or MNP. • In example A13, Schulze STV chooses KT. The first S=2 candidates of Schulze proportional ranking are IT. • In example A34, Schulze STV chooses ABCDEFGHJKMN. The first S=12 candidates of Schulze proportional ranking are ABCDEFHJKLMN.
