paretoFrontKneeIndex: Find the knee of a two dimensional pareto front
Description
Given a matrix m of two rows and n columns, representing solutions of a
two-dimensional optimization problem, returns the column index of the point with
minimum euclidean distance to the utopia point. The utopia point is the point
consisting of the row minima of m. NA or NaN values of
m are ommited.
Usage
paretoFrontKneeIndex(m, normalize = TRUE)
Arguments
m
A matrix of two rows and n columns, representing the solutions of a
two-dimensional optimization problem.
normalize
Whether to normalize both objectives to the interval of
[0, 1], defaults to TRUE.
Value
The knee point index, i.e. the column index in m of the point of minimum
euclidean distance to the utopia point.
