Returns a set (list) of the increasing sets (integer vectors) of the input
vector v
, in the sense that the first set contains the first element
of v
, the second set the first and second elements of v
, and so
on.
closest_subsets(v)
A list of the same length as the input. The first element of the list is v[1], the second is sort(v[1:2]), the third sort(v[1:3]), and so on.
An integer vector. Meant to represent the \(k\) nearest neighbors of a location, the first element being the integer identifier of the location itself.
