-/** This interface specifies how to check if a {@link

- * algorithm to stop its search according to the problem at hand.</p>

- * {@link SimpleVectorValueChecker} and {@link SimplePointChecker<PointVectorValuePair>}. The first
- * one considers convergence is reached when the objective function value does not
- * change much anymore, it does not use the point set at all. The second one
- * considers convergence is reached when the input point set does not change
- * much anymore, it does not use objective function value at all.</p>
