LevyWalk

class LevyWalk<T> @JvmOverloads constructor(reaction: NodeReaction<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.

@JvmOverloads

constructor(reaction: NodeReaction<T>, environment: Environment<T, Euclidean2DPosition>, randomGenerator: RandomGenerator, speed: Double, scale: Double = 1.0, shape: Double = 1.0)

Properties

environment

open val environment: Environment<T, Euclidean2DPosition>

the environment where the node moves

reaction

override val reaction: NodeReaction<T>

The NodeReaction owning this action, hosted by targetNode.

targetNode

val targetNode: Node<T>

Functions

cloneAction

override fun cloneAction(newReaction: Reaction<T>): Action<T>

Creates an equivalent action owned by newReaction, such as a reaction cloned onto a new node. An action targeting the host of its reaction targets the host of newReaction, which must then be a Node; an action targeting any other node keeps its target.

execute

open override fun execute()

Moves the node according to getNextPosition, in absolute or relative coordinates depending on isAbsolute.

getNextPosition

override fun getNextPosition(): Euclidean2DPosition

The next position to reach, in absolute or relative coordinates depending on isAbsolute.

shouldEqual

infix fun Action<*>.shouldEqual(other: Action<*>)

toString

open override fun toString(): String
