QuadraticFunction - Class in de.jstacs.algorithms.optimization

This class implements a quadratic function.

QuadraticFunction(double, double, double) - Constructor for class de.jstacs.algorithms.optimization.QuadraticFunction

This constructor creates a quadratic function with: a*x2 + b*x + c.

QuadraticFunction(double, double, double, double, double, double) - Constructor for class de.jstacs.algorithms.optimization.QuadraticFunction

This constructor creates an instance from 3 points (x,f(x)).

QUASI_NEWTON_BFGS - Static variable in class de.jstacs.algorithms.optimization.Optimizer

This constant can be used to specify that the quasi-Newton method of Broyden-Fletcher-Goldfarb-Shanno should be used in the optimize-method.

QUASI_NEWTON_DFP - Static variable in class de.jstacs.algorithms.optimization.Optimizer

This constant can be used to specify that the quasi-Newton method of Davidon-Fletcher-Powell should be used in the optimize -method.

quasiNewtonBFGS(DifferentiableFunction, double[], TerminationCondition, double, StartDistanceForecaster, OutputStream, Time) - Static method in class de.jstacs.algorithms.optimization.Optimizer

The Broyden-Fletcher-Goldfarb-Shanno version of the quasi-Newton method.

quasiNewtonDFP(DifferentiableFunction, double[], TerminationCondition, double, StartDistanceForecaster, OutputStream, Time) - Static method in class de.jstacs.algorithms.optimization.Optimizer

The Davidon-Fletcher-Powell version of the quasi-Newton method.
