Interface BatchLSObserver


  • public interface BatchLSObserver
    Observer for batch least squares estimator iterations.

    This interface is intended to be implemented by users to monitor the progress of the estimator during estimation.

                                 int evaluationsCount,
                                 Orbit[] orbits,
                                 ParameterDriversList estimatedOrbitalParameters,
                                 ParameterDriversList estimatedPropagatorParameters,
                                 ParameterDriversList estimatedMeasurementsParameters,

                                 org.hipparchus.optim.nonlinear.vector.leastsquares.LeastSquaresProblem.Evaluation lspEvaluation)
        Notification callback for the end of each evaluation.
        Parameters:
        iterationsCount - iterations count
        evaluationsCount - evaluations count
        orbits - current estimated orbits
        estimatedOrbitalParameters - estimated orbital parameters
        estimatedPropagatorParameters - estimated propagator parameters
        estimatedMeasurementsParameters - estimated measurements parameters
        evaluationsProvider - provider for measurements evaluations resulting from the current estimated orbit (this is an unmodifiable view of the current evaluations, its content is changed at each iteration)
        lspEvaluation - current evaluation of the underlying least squares problem
