NthElement is an algorithm for finding the n-th largest element of a list.
In this case, only one of the components of the measurement vectors is considered. This component is defined by the argument activeDimension. The search is restricted to the range between the index begin and end, also passed as arguments. This algorithm was based on the procedure used in the STL nth_element method.

| unsigned int | activeDimension, | ||

| const typename TSubsample::MeasurementType | partitionValue | ||
| ) |
The Partition algorithm performs partial sorting in a sample.
Given a partitionValue, the algorithm moves to the beginning of the sample all MeasurementVectors whose component activeDimension is smaller than the partitionValue. In this way, the sample is partially sorted in two groups. First the group with activeDimension component smaller than the partitionValue, then the group of MeasurementVectors with activeDimension component larger than the partitionValue. The Partition algorithm takes as input a sample, and a range in that sample defined by [beginIndex,endIndex]. Only the activeDimension components of the MeasurementVectors in the sample will be considered by the algorithm. The Algorithm return an index in the range of [beginIndex,endIndex] pointing to the element with activeDimension component closest to the partitionValue.
The endIndex should points one point after the last elements if multiple partitionValue exist in the sample the return index will points the middle of such values. Implemented following the description of the partition algorithm in the QuickSelect entry of the Wikipedia.

QuickSelect is an algorithm for finding the k-th largest element of a list.
In this case, only one of the components of the measurement vectors is considered. This component is defined by the argument activeDimension. The search is rectricted to the range between the index begin and end, also passed as arguments.
The endIndex should point one point after the last elements. Note that kth is an index in a different scale than [beginIndex,endIndex]. For example, it is possible to feed this function with beginIndex=15, endIndex=23, and kth=3, since we can ask for the element 3rd in the range [15,23]. In this version, a guess value for the median index is provided in the argument medianGuess. The algorithm returns the value of the activeDimension component in the MeasurementVector located in the kth position.
