Method Detail

dominates

public boolean dominates(Objectives o1,
                         Objectives o2)

Checks two Objectives for domination. The dominance relation is Pareto-Domination.

Specified by:

dominates in interface DominationStrategy

Parameters:

o1 - the objectives to check

o2 - the objectives to compare with

Returns:

true, if o1 dominates o2
false, otherwise

dominates

public boolean dominates(double[] va,
                         double[] vb)

dominates(org.opt4j.core.Objectives, org.opt4j.core.Objectives)

Parameters:

va - array of objective values

vb - array of objective values

Returns:

true, if va dominates vb,
false, otherwise

weaklyDominates

public boolean weaklyDominates(Objectives o1,
                               Objectives o2)

Checks two Objectives for weak domination. The dominance relation is Pareto-Domination.

Specified by:

weaklyDominates in interface DominationStrategy

Parameters:

o1 - the objectives to check

o2 - the objectives to compare with

Returns:

true, if o1 weakly dominates o2
false, otherwise

weaklyDominates

public boolean weaklyDominates(double[] va,
                               double[] vb)

weaklyDominates(org.opt4j.core.Objectives, org.opt4j.core.Objectives)

Parameters:

va - array of objective values

vb - array of objective values

Returns:

true, if va weakly dominates vb,
false, otherwise
