Detailed Description

A temporary cell object used in the NolfiEncoding encoding method.

The NolfiCells are always contained in a NolfiNet. The cell has an ability to sprout a L-System axon tree from itself, where the shape of the tree is determined by parameters encoded in the genome.

Member Function Documentation

void addGenesTo (  Gentainer &    g,
int    i,
int    types,
int    xsize,
int    ysize,
const StringMap &    params
)  [static]
 

Add the genes for a single cell (with given index) to the given genome.

Parameters:
g  Genetic container where the genes are placed. This is typically NolfiEncoding.
i  Index number of the gene. It will be used during ontogenesis to access the gene.
types  The number of different neuron types in the genome. The values are always a power of two; typical values are 8, 16, 32, 64.
xsize  X-dimension of the cellular space of the encoding method. A power of two. Typical value is 16.
ysize  Y-dimension of the cellular space of the encoding method. Typical value is 16.
params  Other params in a String Map.

void check (    ) 
 

Implementation for Object.

Definition at line 297 of file nolfinet.cc.

void decodeFrom (  const Gentainer &    g,
int    i
) 
 

Read the cell with given index description from given genetic container.

Parameters:
g  Genetic container that contains the genes to individualize the cell.
i  The identifier number for the cell. Same as in addGenesTo.

void developAxon (  Array< Coord2D > &    result,
double    scale
)  const
 

Grows an "axon tree" L-System from the cell.

References NolfiTurtle::getTips().

void drawEPS (  EPSDevice &    dc,
double    scale
)  const
 

Draws the image of the cell and it's axon tree into the given graphics driver.

Parameters:
dc  Encapsulates PostScript graphics driver.
scale  Drawing scale. The size of the image is multiplied by this factor.

Definition at line 284 of file nolfinet.cc.

void make (    ) 
 

Initializes the cell.

Reimplemented in CangelosiCell.

Definition at line 147 of file nolfinet.cc.

void mapTo (  int    neuron )  [inline]
 

The NolfiCell is an temporary object.

The internal neuron index tells it's identity in the final network. If the value is EMPTYID (-1), the neuron will not exist in the final network.

Definition at line 99 of file nolfinet.h.

const Coord2D& pos (    )  const [inline]
 

Returns:
The 2-dimensional coordinates of the cell in the cell space.

Definition at line 75 of file nolfinet.h.

void setPos (  double    x,
double    y
)  [inline]
 

Sets the coordinates of the cell in the cell space.

See also:
setPos(const Coord2D& npos)

Definition at line 85 of file nolfinet.h.

void setPos (  const Coord2D &    npos )  [inline]
 

Sets the coordinates of the cell in the cell space.

See also:
setPos(double x, double y)

Definition at line 80 of file nolfinet.h.

void setTipRadius (  double    r )  [inline]
 

Sets the connection radius of the axon tips.

This radius determines how far away the tip can be from another neuron to create an actual connection.

Parameters:
r  Typical values for the radius are 0.5...10.
