Completion method

From electowiki

A completion method is a method at the end of a chain of election methods. For example, in the "Smith//Score" style of aggregate methods, the "Smith set" is calculated first, and then if there is more than one member of that set, the desired number of winners (usually a single winner) is chosen (with the same ballots) using score voting. Hence score voting is the "completion method" (as the second method) in the "Smith//Score" aggregate method.
