Fast non-dominated sorting algorithm proposed by Deb. Non-dominated sorting expects a set of points and returns a set of non-dominated fronts. In short words this is done as follows: the non-dominated points of the entire set are determined and assigned rank 1. Afterwards all points with the current rank are removed, the rank is increased by one and the procedure starts again. This is done until the set is empty, i.~e., each point is assigned a rank.
doNondominatedSorting(x)
[list
]
List with the following components
Integer vector of ranks of length ncol(x)
. The higher
the rank, the higher the domination front the corresponding point is
located on.
Integer vector of length ncol(x)
. The i-th element
is the domination number of the i-th point.
[matrix
]
Numeric matrix of points. Each column contains one point.
