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.

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). ERC's should override and generate a new object with a new value.

Parameters:

sptr

to this primitive

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

Definition at line 36 of file Primitive.cpp.

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). (ERC's should override and make a new copy of the original object).

Parameters:

sptr

to this primitive

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

Definition at line 60 of file Primitive.cpp.

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.

Implemented in Tree::MyTerminal, Tree::MyFunc, Tree::Primitives::AddT< T >, Tree::Primitives::Cos, Tree::Primitives::DivT< T >, Tree::Primitives::MaxT< T >, Tree::Primitives::MinT< T >, Tree::Primitives::MulT< T >, Tree::Primitives::NegT< T >, Tree::Primitives::PosT< T >, Tree::Primitives::Sin, Tree::Primitives::SubT< T >, Tree::Primitives::TerminalT< T >, Tree::Primitives::ERC< T >, IfFoodAhead, MoveAhead, Prog2, Prog3, TurnLeft, TurnRight, and Tree::Primitives::ERC< double >.

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

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

Parameters:

	result	result of the operation
	tree	reference to current tree

Definition at line 71 of file Primitive.cpp.

void Tree::Primitives::Primitive::skipNextArgument ( Tree & tree )

Skip next child subtree (doesn't execute the subtree).

Parameters:

tree

reference to current tree
