Enum Constants

Enum Constant	Description
EXPONENTIAL	Exponential decay (Ebbinghaus-inspired).
LINEAR	Linear decay: score decreases linearly over time.
NONE	No decay - all memories retain full importance.

Enum Constant Details

NONE

public static final ForgettingCurve NONE

No decay - all memories retain full importance.

LINEAR

public static final ForgettingCurve LINEAR

Linear decay: score decreases linearly over time.

EXPONENTIAL

public static final ForgettingCurve EXPONENTIAL

Exponential decay (Ebbinghaus-inspired).

Method Details

values

public static ForgettingCurve[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static ForgettingCurve valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null

decay

public abstract double decay(double currentScore,
 Duration age)

Calculates the decayed score based on age.

Parameters:

currentScore - Current importance score (0.0 - 1.0)

age - How old the memory is

Returns:

Decayed score
