PAIR
- Type of the (point, value) pair.
The type of the "value" part of the pair (not used by this class).@Deprecated public class SimplePointChecker<PAIR extends Pair<double[],? extends Object>> extends AbstractConvergenceChecker<PAIR>
ConvergenceChecker
interface using
only point coordinates.
Convergence is considered to have been reached if either the relative
difference between each point coordinate are smaller than a threshold
or if either the absolute difference between the point coordinates are
smaller than another threshold.
converged
method will also return
true
if the number of iterations has been set (see
