| * This interface represents an estimation problem. |
| * |
| * <p>This interface should be implemented by all real estimation |
| * problems before they can be handled by the estimators through the |
| * {@link Estimator#estimate Estimator.estimate} method.</p> |
| * |
| * <p>An estimation problem, as seen by a solver is a set of |
| * parameters and a set of measurements. The parameters are adjusted |
| * during the estimation through the {@link #getUnboundParameters |
| * getUnboundParameters} and {@link EstimatedParameter#setEstimate |
| * EstimatedParameter.setEstimate} methods. The measurements both have |
| * a measured value which is generally fixed at construction and a |
| * theoretical value which depends on the model and hence varies as |
| * the parameters are adjusted. The purpose of the solver is to reduce |
| * the residual between these values, it can retrieve the measurements |
| * through the {@link #getMeasurements getMeasurements} method.</p> |
