In xegaSelectGene: Selection of Genes and Gene Representation Independent Functions

Factory for a 2-dimensional quadratic parabola.

Description

This list of functions sets up the problem environment for a 2-dimensional quadratic parabola.

Usage

Parabola2DFactory()

Details

The factory contains examples of all functions which form the interface of a problem environment to the simple genetic algorithm with binary-coded genes of package xega.

Value

A problem environment represented as a list of functions:

• $name(): The name of the problem environment.

• $bitlength(): The vector of the number of bits of each parameter of the function.

• $genelength(): The number of bits of the gene.

• $lb(): The vector of lower bounds of the parameters.

• $ub(): The vector of upper bounds of the parameters.

• $f(parm, gene=0, lF=0)): The fitness function.

Additional elements:

• $describe(): Print a description of the problem environment to the console.

• $solution(): The solution structure. A named list with minimum, maximum and 2 lists of equivalent solutions: minpoints, maxpoints.
