Create(TCollection)

Initializes a new instance of the TRSGPIndividual<T> class. (Overrides RSGeneticBase.TRSIndividual.Create(TCollection).)

Destroy

Represents the destructor of the TRSGPIndividual<T> class. (Overrides RSGeneticBase.TRSIndividual.Destroy.)

AdjustedFitness

Represents property AdjustedFitness. (Inherited from RSGeneticBase.TRSIndividual.)

Collection

Returns the population that this individual belongs to.
 

DNA

Represents the genetic code of the individual, its DNA as a program tree of functions, constants, and variables.

Fitness

The Fitness property is a floating point value that specifies the correctness of the individual DNA. Fitness is used by the genetic components to decide which individuals are better than others. Fitness is a score you define for every individual using an     OnEvaluateFitness event handler. It may be any floating point number. However, fitness must have relative meaning among the entire range of assigned fitness numbers, e.g., a fitness of -10 must be worse than a fitness of -3 which must be worse than a fitness of 5, etc (or vice versa, the     FitnessMethod property tells the genetic component whether lower or higher numbers are desirable). The     NormalizedFitness value is the fitness of the individual normalized over the entire population's fitness values so that it is a value between 0 and 1 (where 0 will be the individual with the lowest fitness and 1 will be the individual with the highest fitness).

Using each individual's calculated fitness and the FitnessMethod, the genetic component will seek to either maximize the solution (e.g., keep evolving for individuals whose fitness are greater than other individuals in the population) or to minimize the solution (e.g., find the individuals whose fitness are less than other individuals).
 

FlattenedDNA

Represents property FlattenedDNA.

Name

Allows you to provide a descriptive name for the individual. The genetics components do not use this property. (Inherited from RSGeneticBase.TRSIndividual.)

NeedFitness

Represents property NeedFitness. (Inherited from RSGeneticBase.TRSIndividual.)

NormalizedFitness

Returns the Fitness of the individual normalized over the entire population's fitness values so that it is a value between 0 and 1 (where 0 will be the individual with the lowest fitness and 1 will be the individual with the highest fitness).
 (Inherited from RSGeneticBase.TRSIndividual.)

NormalizedWeigthedFitness

Returns the   WeightedFitness of the individual normalized over the entire population's weighted fitness values so that it is a value between 0 and 1 (where 0 will be the individual with the lowest weighted fitness and 1 will be the individual with the highest weighted fitness). (Inherited from RSGeneticBase.TRSIndividual.)

WeightedFitness

Returns the Fitness value weighted by some function. Use the RSGeneticBase.TRSCustomGeneticComponent.OnEvaluateWeightedFitness event to specify the weighting.

The genetic components can guide the search for the best individual by using the weighted fitness instead of the regular fitness. The weighted fitness allows optimization for something other than the pure fitness. For example, with genetic programming, the weighted fitness can be used to weight the fitness for smaller programs. The     FitnessMethod specifies whether the Fitness or the WeightedFitness is used in the search.

Note that the Fitness is always used for determining if we have found the "best" individual for termination purposes.

Assign(TPersistent)

Overloaded. Represents method Assign(TPersistent). (Overrides RSGeneticBase.TRSIndividual.Assign(TPersistent).)

AssignDNA(TNode)

Replaces the current   DNA tree with the aDNA parameter. The old DNA tree is deleted and freed.

Clone

Returns an exact copy of the current individual. (Inherited from RSGeneticBase.TRSIndividual.)

CreateDNA

Represents method CreateDNA.

Crossover(TNode,TRSGPIndividual<T>,TNode)

Represents method Crossover(TNode,TRSGPIndividual<T>,TNode).

DoSelectNode(TNodeList,TGAFloat)

Overloaded. Represents method DoSelectNode(TNodeList,TGAFloat).

EvaluateFitness

Evaluates the     Fitness of the individual. The fitness function is supplied in the RSGeneticBase.TRSCustomGeneticComponent.OnEvaluateFitness event.

Normally, the Fitness is only evaluated if the individual is modified. This function forces evaluation.

Execute(TRSGPContext<T>)

Executes the individual's genetic program (     DNA) using the specified context. The Context provides program state information (including variable values).

The function returns a value of type T

FlattenDNA

Flattens the DNA tree into a list of nodes. Used by the genetic programming component for various uses, such as selecting a node

You should not have to call the FlattenDNA method yourself.

GetDisplayName

Represents method GetDisplayName. (Inherited from RSGeneticBase.TRSIndividual.)

Graft(TNode,TNode)

Replaces old node with the new node. The old node and its children are NOT deleted or freed

LoadFromXML(IXMLIndividualType)

Overloaded. Reads the individual from the XML node, including   DNA

LoadFromXML(IXMLNode)

Overloaded. Reads the individual's data from the XML node (Overrides RSGeneticBase.TRSIndividual.LoadFromXML(IXMLNode).)

Modified

Informs the object that you have modified it so that its Fitness must be reevaluated (Inherited from RSGeneticBase.TRSIndividual.)

SaveToXML(IXMLIndividualType)

Overloaded. Saves the individual to the XML node, including   DNA

SaveToXML(IXMLNode)

Overloaded. Writes the individual's data to the XML node (Overrides RSGeneticBase.TRSIndividual.SaveToXML(IXMLNode).)

SelectNode(Integer,Boolean)

Overloaded. Selects a random node from the   DNA program tree that does not exceed the Size or Depth limit (specified by the Limit parameter). The IsSizeLimit parameter controls which limit is used.

SelectNode(TGAFloat)

Overloaded. Selects a random node from the   DNA program tree. The FunctionProbability parameter controls how much to prefer non-terminals (functions) over terminals (constants, variables, and functions with arity=0)

SelectNode(TGAFloat,TGPGeneticInstructions)

Overloaded. Selects a random node from the   DNA program tree that is of the same instruction types as in the Instructions parameter. The FunctionProbability parameter controls how much to prefer non-terminals (functions) over terminals (constants, variables, and functions with arity=0)
