Compute the closed crowding distance
the set of point
the crowding distance of each point in the same order as the input sequence
Compute the closed crowding distance of the i-th point in the data points
Compute the closed crowding distance of the i-th point in the data points
the set of point
the closed crowding distance of the point relative to the data
Modification of the crowding distance to avoid infinite values for the first and last point in each domain. The crowding for the second and last element of each domain is instead the distance between the first and second (or last and second but last).
