@Deprecated public class SimpleValueChecker extends AbstractConvergenceChecker<PointValuePair>
ConvergenceChecker interface using
only objective function values.
Convergence is considered to have been reached if either the relative
difference between the objective function values is smaller than a
threshold or if either the absolute difference between the objective
function values is smaller than another threshold.
converged
method will also return true if the number of iterations has been set
(see this constructor).| Constructor and Description |
