A list of vectors |
Details
Similar to PowerRelation()
, SocialRanking
expects expects a list to represent a power relation.
Unlike PowerRelation()
however, this list should not be nested and should only contain vectors, each vector containing elements that are deemed equally preferable.
Use doRanking()
to rank elements based on arbitrary score objects.
A social ranking solution, or ranking solution, or solution, maps each power relation between coalitions to a power relation between its elements.
I.e., from the power relation , we may expect the result of a ranking solution
to rank element 2 over 1. Therefore
will be present, but not
.
Formally, a ranking solution is a function that,
given a power relation
, always produces a power relation
(or
) over its set of elements.
For two elements
,
means that applying the solution
on the ranking
makes
at least as preferable as
.
Often times
and
are used to indicate its symmetric and asymmetric part, respectively.

whereas

Value
A list of type SocialRanking
.
Each element of the list contains a vector of elements in powerRelation$elements
that are indifferent to one another.
