Interface Minimizer

All Known Subinterfaces:

ConstrainedMinimizer

All Known Implementing Classes:

CGMinimizer, PenaltyConstrainedMinimizer

public interface Minimizer

The interface for unconstrained function minimizers. Implementations may also vary in their requirements for the arguments. For example, implementations may or may not care if the initial feasible vector turns out to be non-feasible (or null!). Similarly, some methods may insist that objectives and/or constraint Function objects actually be DiffFunction objects.

Since:

Method Summary

double[]

minimize(Function function, double functionTolerance, double[] initial) Attempts to find an unconstrained minimum of the objective function starting at initial, within functionTolerance.

Method Detail

minimize

public double[] minimize(Function function,
                         double functionTolerance,
                         double[] initial)

Attempts to find an unconstrained minimum of the objective function starting at initial, within functionTolerance.

Parameters:

function - the objective function

functionTolerance - a double value

initial - a initial feasible point
