C# Class AForge.Genetic.ExtendedGeneFunction

Genetic programming gene, which represents arithmetic functions, common mathematical functions and arguments.

Extended gene function may represent arithmetic functions (+, -, *, /), some common mathematical functions (sin, cos, ln, exp, sqrt) or an argument to functions. This class is used by Genetic Programming (or Gene Expression Programming) chromosomes to build arbitrary expressions with help of genetic operators.

Méthodes publiques

Méthode	Description
Clone ( ) : IGPGene	Clone the gene. The method clones the chromosome returning the exact copy of it.
CreateNew ( ) : IGPGene	Creates new gene with random type and value. The method creates new randomly initialized gene . The method is useful as factory method for those classes, which work with gene's interface, but not with particular gene class.
CreateNew ( GPGeneType type ) : IGPGene	Creates new gene with certain type and random value. The method creates new gene with specified type, but random value. The method is useful as factory method for those classes, which work with gene's interface, but not with particular gene class.
ExtendedGeneFunction ( int variablesCount ) : System	Initializes a new instance of the ExtendedGeneFunction class. The constructor creates randomly initialized gene with random type and value by calling Generate( ) method.
ExtendedGeneFunction ( int variablesCount, GPGeneType type ) : System	Initializes a new instance of the ExtendedGeneFunction class. The constructor creates randomly initialized gene with random value and preset gene type.
Generate ( ) : void	Randomize gene with random type and value. The method randomizes the gene, setting its type and value randomly.
Generate ( GPGeneType type ) : void	Randomize gene with random value. The method randomizes a gene, setting its value randomly, but type is set to the specified one.
ToString ( ) : string	Get string representation of the gene.
