org.apache.commons.math.optimization.SimpleVectorialPointChecker
Simple implementation of the {@link VectorialConvergenceChecker} interface usingonly 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.
