Arity

Specifies the Arity (maximum allowed number of children) for the instruction. If Arity is greater than 0, the instruction must be a function

Collection

Specifies the set of instructions that this instruction belongs to

Comment

Specifies a comment about the instruction. This property is not used by the genetic programming engine (except for reading and writing the comment).

Use this property for describing the instruction and what it does or means

Name

Specifies the name of the instruction

OnExecute

Occurs when the instruction is executed. Define an OnExecute event handler for every instruction which is a function

OnInitialize

Occurs when the instruction is initialized at the start of evolution. Use this event to seed the initial constant   Value for the instruction.

Operation

Specifies the type of the instruction: function, variable or constant

Value

Specifies the initial constant value for this instruction (if it is a constant).

Assign(TPersistent)

Represents method Assign(TPersistent).

AssignEvents(TPersistent)

Copies the event handlers in the Source object to the instructions events

DoExecute(TRSGPNode<T>,TRSGPContext<T>)

Represents method DoExecute(TRSGPNode<T>,TRSGPContext<T>).

Execute(TRSGPNode<T>,TRSGPContext<T>)

Executes the node using the specified context. The node provides information about the constant value (if the instruction is a constant) and the subtree program of the node. The Context provides program state information (including variable values).

The function returns a value of type T (which is the result of the OnExecute event, the Node.Value if it is a constant, or the variable value from the Context if is a variable)

GetDisplayName

Represents method GetDisplayName.

Initialize

Initializes the instruction at the start of the genetic evolution (not the start of executing a genetic program). The function calls the OnInitialize event.

The intent of the Initialize method is to initialize the instruction for evolution; usually, this means provide an initial constant     Value.

LoadFromXML(IXMLInstructionType)

Loads the instruction from the XML

LoadValueFromXML(IXMLInstructionType)

Loads the   Value from the XML

OperationChanged

Represents method OperationChanged.

SaveToXML(IXMLConstantInstructionType)

Overloaded. Saves the instruction as a constant to the XML

SaveToXML(IXMLFunctionInstructionType)

Overloaded. Saves the instruction as a function to the XML

SaveToXML(IXMLGPInstructions)

Overloaded. Saves the Instruction to the XML as a function, variable or constant based on its   Operation

SaveToXML(IXMLVariableInstructionType)

Overloaded. Saves the instruction as a variable to the XML

SaveValueToXML(IXMLInstructionType)

Saves the   Value to the XML

ToString

Returns string representation of the instruction
