Enum Constant Summary

Enum Constants

Enum Constant	Description
COVERED_AREA	This fitness method computes the quotient between the trace length and the sum of explored areas.
MAX_AREA	The max area method computes the fitness based on the competitive ratio of explored space divided by the path's length.
MULTI	The multi method computes the fitness based on the competitive ratio of finding a set of distinct treasure points.
SINGULAR	The singular method computes the fitness based on the competitive ratio of finding one distinct treasure point.
SPIRAL	The spiral likeness fitness uses the rotation independent spiral likeness mesaure.
WORST_CASE	The worst case method computes the fitness based on the maximum length over all points to find their worst-case treasure (when the treasure is just an epsilon further away from the origin than the point).
WORST_MEAN	This fitness method calculates the mean of the worst cases for each point of the strategy.

WORST_CASE

public static final Evolution.Fitness WORST_CASE

The worst case method computes the fitness based on the maximum length over all points to find their worst-case treasure (when the treasure is just an epsilon further away from the origin than the point).

WORST_MEAN

public static final Evolution.Fitness WORST_MEAN

This fitness method calculates the mean of the worst cases for each point of the strategy.

MAX_AREA

public static final Evolution.Fitness MAX_AREA

The max area method computes the fitness based on the competitive ratio of explored space divided by the path's length.

COVERED_AREA

public static final Evolution.Fitness COVERED_AREA

This fitness method computes the quotient between the trace length and the sum of explored areas.

SPIRAL

public static final Evolution.Fitness SPIRAL

The spiral likeness fitness uses the rotation independent spiral likeness mesaure.

Method Detail

values

public static Evolution.Fitness[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (Evolution.Fitness c : Evolution.Fitness.values())
    System.out.println(c);

Returns:

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

valueOf

public static Evolution.Fitness valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (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 type has no constant with the specified name

NullPointerException - if the argument is null
