We say that a numeric vector x of length n_x is weakly dominated by y of length n_y iff
n_x=n_y and
for all i=1,…,n_x it holds x_i≤ y_i.
This relation is a preorder: it is reflexive (see rel_is_reflexive
)
and transitive (see rel_is_transitive
),
but not necessarily total (see rel_is_total
).
See rel_graph
for a convenient function
to calculate the relationship between all pairs of elements
of a given set.
Such a preorder is tightly related to classical aggregation functions: each aggregation function is a morphism between weak-dominance-preordered set of vectors and the set of reals equipped with standard linear ordering.
Returns a single logical value
indicating whether x
is weakly
dominated by y
