Class BrentOptimizer

java.lang.Object

org.apache.commons.math.ConvergingAlgorithmImpl

org.apache.commons.math.optimization.univariate.AbstractUnivariateRealOptimizer

org.apache.commons.math.optimization.univariate.BrentOptimizer

All Implemented Interfaces:

ConvergingAlgorithm, UnivariateRealOptimizer

public class BrentOptimizer
extends AbstractUnivariateRealOptimizer

Implements Richard Brent's algorithm (from his book "Algorithms for Minimization without Derivatives", p. 79) for finding minima of real univariate functions. This implementation is an adaptation partly based on the Python code from SciPy (module "optimize.py" v0.5).

Since:

2.0
