Detailed Description

template<class T>
class Tree::Primitives::ERC< T >

Ephemereal random constant (ERC) node class (Tree genotype).

ERC is a Primitive that represents a single value (of type double by default) that can assume values from the interval or from the set. Value of an ERC instance is defined once - when assigning to a node in a new tree. Only double-typed ERC instances may change value (with Gaussian mutation).

ERCs are distinguished from regular terminals by the prefix denoting their type, e.g.: D_3.14, I_5, B_true, C_a

Tree::Primitives::ERC< T >::ERC ( )

inline

Member Function Documentation

assignToNode()

template<class T>

PrimitiveP Tree::Primitives::ERC< T >::assignToNode ( PrimitiveP primitive )

inlinevirtual

Create (or choose) new unique ERC value and assign to tree node.

Parameters

pointer

to destination

Reimplemented from Tree::Primitives::Primitive.

Reimplemented in Tree::Primitives::ERCD.

Definition at line 160 of file Terminal.h.

copyWithNode()

template<class T>

PrimitiveP Tree::Primitives::ERC< T >::copyWithNode ( PrimitiveP primitive )

inlinevirtual

Copy primitive (when copying a node, e.g. in crossover). The default behaviour just returns the same pointer (common primitives). (ERCs should override and make a new copy of the original object).

Parameters

sptr	to this primitive

Reimplemented from Tree::Primitives::Primitive.

Definition at line 151 of file Terminal.h.

execute()

template<class T>

void Tree::Primitives::ERC< T >::execute ( void * result, Tree & tree )

inlinevirtual

Execute the primitive.

Function primitives gather arguments and return a value; terminal primitives return current value.

Implements Tree::Primitives::Primitive.

Definition at line 124 of file Terminal.h.

getValue()

template<class T>

void Tree::Primitives::ERC< T >::getValue ( void * value )

inlinevirtual

Get terminal's value.

Parameters

pointer

to destination

Reimplemented from Tree::Primitives::Primitive.

Definition at line 145 of file Terminal.h.

initialize()

template<class T>

bool Tree::Primitives::ERC< T >::initialize ( StateP state )

inlinevirtual

Initialize ERC value(s).

Read given values from config and store in vector.

Reimplemented from Tree::Primitives::Primitive.

Reimplemented in Tree::Primitives::ERCD.

Definition at line 103 of file Terminal.h.

setValue()

template<class T>

void Tree::Primitives::ERC< T >::setValue ( void * value )

inlinevirtual

Set terminal's value.

Parameters

value

pointer to new value

Reimplemented from Tree::Primitives::Primitive.

Definition at line 135 of file Terminal.h.

Member Data Documentation

baseName_

template<class T>

std::string Tree::Primitives::ERC< T >::baseName_

Definition at line 88 of file Terminal.h.

template<class T>

T Tree::Primitives::ERC< T >::value_

Definition at line 89 of file Terminal.h.

values_

template<class T>

std::vector<T>* Tree::Primitives::ERC< T >::values_

protected

Placeholder for predefined values that this type of ERC may assume. Each ERC instance holds only a single value.
