Detailed Description

Class implements concrete component of SmootherCostFunction.

SmootherCostFunction implements cost function used by optimization algorithm in swap curve bootstrapping. The mathematical form of cost function is defined in classes that inherits from CostFunctionDecorator. Choosing appropriate decorators, we can minimize for example the length of the swap curve etc.

This class specifies what we actually mean by swap curve. Swap curve can be defined by set of discount factors, zero-coupon rates, forwards rates etc. Choosing this class as base class for CostFunction decorator, we will optimize the zero coupon rates.

SmoothZeroouponRates is a concrete component in decorator structure. Concrete Component is a class that contains basic behaviour that can be altered by decorators.
