Method Details

diffusionAndEvaporationUpdateKernel

public void diffusionAndEvaporationUpdateKernel()

Description copied from interface: Pheromone

Apply the diffusion update and evaporation processes at once. This method is called after the Pheromone.diffuseValuesToTmpGridKernel() method in the Pheromone.diffusionAndEvaporation() method.

Specified by:

diffusionAndEvaporationUpdateKernel in interface Pheromone<Float>

Overrides:

diffusionAndEvaporationUpdateKernel in class CudaPheromone

getMaxDirection

public int getMaxDirection(int i,
 int j)

Description copied from interface: Pheromone

Returns the direction with the maximum value

Specified by:

getMaxDirection in interface Pheromone<Float>

Overrides:

getMaxDirection in class CudaPheromone

Parameters:

i - x coordinate

j - y coordinate

Returns:

the direction with the maximum value

getMinDirection

public int getMinDirection(int i,
 int j)

Description copied from interface: Pheromone

Returns the direction with the minimum value

Specified by:

getMinDirection in interface Pheromone<Float>

Overrides:

getMinDirection in class CudaPheromone

Parameters:

i - x coordinate

j - y coordinate

Returns:

the direction with the minimum value

freeMemory

public void freeMemory()

Specified by:

freeMemory in interface CudaObject

Overrides:

freeMemory in class CudaPheromone
