Javadoc

This class adapts the unconstrained nonlinear minimization algorithms in the "minimization" package to the task of estimating locally optimal (minimum-cost) parameter sets. This allows us to use algorithms like BFGS FunctionMinimizerBFGS to find locally optimal parameters of, for example, a DifferentiableFeedforwardNeuralNetwork. Any first-order derivative FunctionMinimizer may be dropped into this class.

My current preference is for using BFGS ( FunctionMinimizerBFGS) to solve virtually all problems. However, when there are too many parameters, then Liu-Storey conjugate gradient ( FunctionMinimizerLiuStorey) is another good choice.

When first-order derivative information is not available, then you may use either automatic differentiation ( GradientDescendableApproximator) or the derivative-free minimization routines, such as those used by ParameterDerivativeFreeCostMinimizer.
