net.finmath.marketdata2.calibration.Solver
public class Solver extends Object
Generates a calibrated model for a given set of calibrationProducts with respect to given CurveFromInterpolationPointss. The model and the curve are assumed to be immutable, i.e., the solver will return a calibrate clone, containing clones for every curve which is part of the set of curves to be calibrated. The calibration is performed as a multi-threaded global optimization. I will greatly profit from a multi-core architecture.
