A specific form of ALLOCATE_ENTITY_FROM_QUEUE.

FIRST_FIT_DECREASING

public static final ConstructionHeuristicType FIRST_FIT_DECREASING

A specific form of ALLOCATE_ENTITY_FROM_QUEUE.

WEAKEST_FIT

public static final ConstructionHeuristicType WEAKEST_FIT

A specific form of ALLOCATE_ENTITY_FROM_QUEUE.

WEAKEST_FIT_DECREASING

public static final ConstructionHeuristicType WEAKEST_FIT_DECREASING

A specific form of ALLOCATE_ENTITY_FROM_QUEUE.

STRONGEST_FIT

public static final ConstructionHeuristicType STRONGEST_FIT

A specific form of ALLOCATE_ENTITY_FROM_QUEUE.

STRONGEST_FIT_DECREASING

public static final ConstructionHeuristicType STRONGEST_FIT_DECREASING

A specific form of ALLOCATE_ENTITY_FROM_QUEUE.

ALLOCATE_ENTITY_FROM_QUEUE

public static final ConstructionHeuristicType ALLOCATE_ENTITY_FROM_QUEUE

Put all entities in a queue. Assign the first entity (from that queue) to the best value. Repeat until all entities are assigned.

ALLOCATE_TO_VALUE_FROM_QUEUE

public static final ConstructionHeuristicType ALLOCATE_TO_VALUE_FROM_QUEUE

Put all values in a round-robin queue. Assign the best entity to the first value (from that queue). Repeat until all entities are assigned.

CHEAPEST_INSERTION

public static final ConstructionHeuristicType CHEAPEST_INSERTION

A specific form of ALLOCATE_FROM_POOL.

ALLOCATE_FROM_POOL

public static final ConstructionHeuristicType ALLOCATE_FROM_POOL

Put all entity-value combinations in a pool. Assign the best entity to best value. Repeat until all entities are assigned.

Method Details

values

public static ConstructionHeuristicType[] 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 ConstructionHeuristicType 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

getDefaultEntitySorterManner

public @NonNull EntitySorterManner getDefaultEntitySorterManner()

getDefaultValueSorterManner

public @NonNull ValueSorterManner getDefaultValueSorterManner()

getBluePrintTypes

public static @NonNull ConstructionHeuristicType @NonNull [] getBluePrintTypes()

Returns:

values() without duplicates (abstract types that end up behaving as one of the other types).
