Constructor Details

MooreGeometry

public MooreGeometry(EvoLudo engine)

Create a Moore square lattice geometry tied to the given engine.

Parameters:

engine - EvoLudo pacemaker

Method Details

parse

public boolean parse(String arg)

Description copied from class: AbstractGeometry

Parse geometry-specific CLI options.

Overrides:

parse in class SquareGeometry

Parameters:

arg - the argument string without the geometry key

Returns:

true if parsing succeeded, false if invalid

init

public void init()

Description copied from class: SquareGeometry

Generates square regular lattices with arbitrary neighbourhood sizes. Variant-specific initializers for standard stencils are available to subclasses.

Requirements/notes:

1. Population size must be a perfect square \(N=n^2\).
2. Admissible connectivities are \(4\) (von Neumann) or \((2m+1)^2-1\) for Moore-type stencils.
3. Inter-species interactions add the focal node as a neighbour and allow connectivity \(1\).
4. Boundaries are periodic by default but can be fixed.

Overrides:

init in class SquareGeometry

initHierarchicalMoore

public static void initHierarchicalMoore(AbstractGeometry geometry,
 int popSize,
 int demeSize,
 int startIndex,
 boolean fixedBoundary)

Initialize one hierarchical Moore square deme using population and deme sizes.

Parameters:

geometry - geometry receiving the links

popSize - total population size

demeSize - number of individuals in the deme

startIndex - index offset into the population

fixedBoundary - true for fixed boundary conditions

initMoore

public static void initMoore(AbstractGeometry geometry,
 int side,
 int fullside,
 int offset,
 boolean fixedBoundary)

Initialize a Moore square lattice.

Parameters:

geometry - geometry receiving the links

side - side length of the (sub) lattice

fullside - global side length

offset - index offset into the population

fixedBoundary - true for fixed boundary conditions

adjustBoundaries

private static void adjustBoundaries(AbstractGeometry geometry,
 int side,
 int fullside,
 int offset,
 boolean interspecies)

Adjust Moore stencils along fixed boundaries.

Parameters:

geometry - geometry receiving the links

side - side length of the (sub) lattice

fullside - global side length

offset - index offset into the population

interspecies - true if self-links are required

checkSettings

protected boolean checkSettings()

Description copied from class: AbstractGeometry

Hook for subclasses to implement geometry specific checks.

Overrides:

checkSettings in class SquareGeometry

Returns:

true if adjustments require a reset
