LevyWalk

class LevyWalk<T> @JvmOverloads constructor(node: Node<T>, reaction: Reaction<T>, environment: Environment<T, Euclidean2DPosition>, randomGenerator: RandomGenerator, speed: Double, scale: Double = 1.0, shape: Double = 1.0) : GenericRandomWalker<T>

Selects a target based on a random direction extracted from randomGenerator, and a random distance extracted from a ParetoDistribution of parameters scale and shape. Moves toward the targets at a constant speed and changes targets on collision.

Functions

cloneAction

open override fun cloneAction(node: Node<T>, reaction: Reaction<T>): LevyWalk<T>

This method allows to clone this action on a new node. It may result useful to support runtime creation of nodes with the same reaction programming, e.g. for morphogenesis.

execute

open fun execute()

Detects if the move is in absolute or relative coordinates, then calls the correct method on the Environment.

getNextPosition

fun getNextPosition(): Euclidean2DPosition?
