PR methods can generally be split into two categories: sequential (one winner is elected at a time) and optimal (every possible winner set is compared to each other and the best one is chosen).
=== Party list case ===
The party list case of a proportional voting method is what type of [[Party list]] allocation method it becomes equivalent to when voters vote in a "Party list"-like manner (i.e. they give maximal support to some candidates and no support to all others, as if voting on party lines). Generally, the party list case of a PR method will either be a [[Divisor method|divisor method]], such as [[D'Hondt]], or a [[Largest remainder method]], such as [[Hamilton]]. PR methods can generally be split into two categories: sequential (one winner is elected at a time) and optimal (every possible winner set is compared to each other and the best one is chosen).
 
Almost all sequential PR methods can have a single-winner method done to elect the final seat; this is because at that point there is only one seat left to elect. See [[Single transferable vote#Deciding the election of the final seat]] for an example. [[Condorcet methods]] and [[STAR voting]] can be made to work with PR methods in this way.
