Class Genotype

java.lang.Object
net.bmahe.genetics4j.core.Genotype
public class Genotype extends Object
Represents a genotype in an evolutionary algorithm, which is a collection of chromosomes.

A genotype encapsulates the complete genetic representation of an individual solution, consisting of one or more chromosomes that together define the individual's characteristics. Each chromosome may represent different aspects or components of the solution space.

Genotypes are immutable once created and provide type-safe access to their constituent chromosomes.
