Examples of ObjectiveFunction

org.apache.commons.math3.optim.nonlinear.scalar.ObjectiveFunction
Scalar function to be optimized. @since 3.1

rinde.sim.pdptw.common.ObjectiveFunction
Instances of this interface define an objective on which a {@link StatisticsDTO} can be measured.
Implementations should not keep any internal state. @author Rinde van Lon
