Interface Summary Interface Description Minimizer<F extends Function<S,?>,S> Interface that finds the minimum value of a function.MinimizerWithGradient<F extends Function<S,?>,G extends Function<S,?>,S> Interface for classes that extends the functionality ofMinimizer
by providing a method that takes a gradient function.NonLinearParameterTransforms Describes the transformation (and its inverse) from a set of n variables (e.g.ParameterLimitsTransform Interface for objects containing functions that can transform constrained model parameters into unconstrained fitting parameters and vice versa.ScalarMinimizer Interface for classes that extend the functionality ofMinimizer
by providing a method that allows the search area for the minimum to be bounded. 
Class Summary Class Description DoubleRangeLimitTransform Limit transform.GoldenSectionMinimizer1D MinimumBracketer NonLinearTransformFunction NullTransform Provides a null implementation of parameter transformation; the functions return unchanged values.ParabolicMinimumBracketer PositiveOrZero A function from a vector x (DoubleArray
to Boolean that returns true iff all the elements of x are positive or zero.SingleRangeLimitTransform If a model parameter $x$ is constrained to be either above or below some level $a$ (i.e.SumToOne For a set of N1 "fit" parameters, produces N "model" parameters that sum to one.UncoupledParameterTransforms For a set of n function parameters, this takes n ParameterLimitsTransform (which can be the NullTransform which does NOT transform the parameter) which transform a constrained function parameter (e.g.
