public class Fibonacci
extends ModelFiniteIntervalSearcher

Class for doing a one-dimensional minimization using Fibonacci division.

To do the optimization, a unimodal interval of the parameter being varied must be specified. The interval is given by the lower and upper bound of the parameter specified in the command file.

Constructor

Parameters:

genOptData - a reference to the GenOpt object.
Note: the object is used as a reference. Hence, the datas of GenOpt are modified by this Class.

Throws:

OptimizerException - if algorithm is used for problems with more than 1 independent variable

java.io.IOException - if an I/O exception occurs

java.lang.Exception

InputFormatException
