Detailed Description

Base primitive class (Tree genotype).

Each node of a tree points to a single primitive, which may be a function or a variable (of Terminal class). Some primitives are shared among all the trees (i.e. have the same value and functionality), but some (like ERC) are owned by a single Tree.

◆ assignToNode()

PrimitiveP Tree::Primitives::Primitive::assignToNode ( PrimitiveP primitive)
virtual

Assign primitive to node (when building a tree). The default behaviour just returns the same pointer (common primitives). ERCs should override and generate a new object with a new value.

Parameters
sptrto this primitive

Reimplemented in Tree::Primitives::ERC< T >, Tree::Primitives::ERC< double >, and Tree::Primitives::ERCD.

Definition at line 36 of file Primitive.cpp.

◆ copyWithNode()

PrimitiveP Tree::Primitives::Primitive::copyWithNode ( PrimitiveP primitive)
virtual

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
sptrto this primitive

Reimplemented in Tree::Primitives::ERC< T >, and Tree::Primitives::ERC< double >.

Definition at line 60 of file Primitive.cpp.

◆ execute()

virtual void Tree::Primitives::Primitive::execute ( void * result,
Tree & tree )
pure virtual

Execute the primitive.

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

◆ getComplementName()

std::string Tree::Primitives::Primitive::getComplementName ( )

Get complement's name.

Definition at line 118 of file Primitive.cpp.

◆ getName()

std::string Tree::Primitives::Primitive::getName ( )

Get primitive's name.

Definition at line 109 of file Primitive.cpp.

◆ getNextArgument()

void Tree::Primitives::Primitive::getNextArgument ( void * result,
Tree & tree )

Execute next child node's primitive (execute next subtree).

Parameters
resultresult of the operation
treereference to current tree

Definition at line 71 of file Primitive.cpp.

◆ getNumberOfArguments()

int Tree::Primitives::Primitive::getNumberOfArguments ( )

Return primitive's number of arguments.

Definition at line 91 of file Primitive.cpp.

◆ getValue()

void Tree::Primitives::Primitive::getValue ( void * value)
virtual

Reimplemented in Tree::Primitives::ERC< T >, Tree::Primitives::ERC< double >, Tree::Primitives::TerminalT< T >, and Tree::Primitives::TerminalT< double >.

Definition at line 48 of file Primitive.cpp.

◆ initialize()

bool Tree::Primitives::Primitive::initialize ( StateP state)
virtual

Initialize the primitive (default just sets the StateP pointer).

Reimplemented in Tree::Primitives::ERC< T >, Tree::Primitives::ERC< double >, and Tree::Primitives::ERCD.

Definition at line 23 of file Primitive.cpp.

◆ setName()

void Tree::Primitives::Primitive::setName ( std::string name)

Set primitive's name.

Definition at line 100 of file Primitive.cpp.

◆ setValue()

void Tree::Primitives::Primitive::setValue ( void * value)
virtual
