public class DblParamSetSimplex
extends java.util.TreeSet
implements Displayable

When doing Simplex optimization it is important to avoid doing lots of sorting. By extending TreeSet we can determine best, worst and next-to-worst points easily.

Method Detail

add

public boolean add(ParameterValuePair X)

Add a ParameterValuePair to the simplex.

remove

public boolean remove(ParameterValuePair X)

Remove a ParameterValuePair from the simplex.

getWorst

public ParameterValuePair getWorst()

Return the worst ParameterValuePair.

getBest

public ParameterValuePair getBest()

Return the best ParameterValuePair.

getNextToWorst

public ParameterValuePair getNextToWorst()

Return the ParameterValuePair that is next to worst.

getNMMean

public DblParamSet getNMMean()

Calculate average of parameter values **ignoring the worst parameter set**.

getFreshNMMean

public DblParamSet getFreshNMMean()

Calculate average of parameter values **ignoring the worst parameter set**.
