Detailed Description

Tree class - implements genotype as a tree.

Tree inherits a vector of Node objects. Each node points to a Primitive object. Nodes in tree are aligned in a prefix notation. Some primitives are shared among all the trees, but some (such as ERC primitives) belong to a single Tree.

Member Function Documentation

void Tree::Tree::execute ( void *  result  ) 

Execute current tree.

Evaluates the function embodied in the tree (or executes the represented program).

Parameters:
result the resulting tree value (of the first node)

Definition at line 362 of file Tree.cpp.

void Tree::Tree::getTerminalValue ( std::string  name,
void *  value 
)

Retrieve a terminal's value.

Parameters:
name terminal's name
value terminal's value

Definition at line 522 of file Tree.cpp.

void Tree::Tree::initializeFirst ( Tree *  hometree  )  [protected]

Performs the first Tree initialization (performed only once for each active Tree Genotype). Constructs the primitive set and performs parameter checks.

Parameters:
hometree uninitialized Tree instance in vector of active Genotypes stored in State

Definition at line 149 of file Tree.cpp.

void Tree::Tree::setTerminalValue ( std::string  name,
void *  value 
)

Set a terminal's value.

Parameters:
name terminal's name
value terminal's value

Definition at line 504 of file Tree.cpp.

void Tree::Tree::update ( void   ) 

Calculate depth and subtree sizes of each node in the tree.

Uses recursive depth-first tree processing.
