org.drip.function.r1tor1solver.FixedPointFinderBrent

public class FixedPointFinderBrent
extends FixedPointFinderBracketing

FixedPointFinderBrent customizes FixedPointFinderBracketing by applying the Brent's scheme of compound variate selector.

Brent's scheme, as implemented here, is described in http://www.credit-trader.org. This implementation retains absolute shifts that have happened to the variate for the past 2 iterations as the discriminant that determines the next variate to be generated.

FixedPointFinderBrent uses the following parameters specified in VariateIterationSelectorParams:

• The Variate Primitive that is regarded as the "fast" method
• The Variate Primitive that is regarded as the "robust" method
• The relative variate shift that determines when the "robust" method is to be invoked over the "fast"
• The lower bound on the variate shift between iterations that serves as the fall-back to the "robust"

• Module = Computational Core Module
• Library = Numerical Analysis Library
• Project = R^d To R^d Function Analysis
• Package = Built-in R¹ To R¹ Solvers
