-/** This interface specifies how to check if an {@link MultivariateRealOptimizer optimization
- * algorithm} has converged.
- *
- * <p>Deciding if convergence has been reached is a problem-dependent issue. The
- * user should provide a class implementing this interface to allow the optimization
- * algorithm to stop its search according to the problem at hand.</p>
- * <p>For convenience, two implementations that fit simple needs are already provided:
- * {@link SimpleScalarValueChecker} and {@link SimpleRealPointChecker}. 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>
