public Context()

Method Details

destroy

public static void destroy()

Destroy the solver context associated with the current thread. Does not affect the context of other threads.

reset

public static void reset()

Recreate the solver context associated with the current thread. Does not affect the context of other threads.

suspendObjectiveTracking

public static Context.ObjectiveTrackingScope suspendObjectiveTracking()

Temporarily suspend automatic objective tracking for the current thread. Suspensions may be nested and should be managed with try-with-resources. The suspension does not propagate to child threads.

Returns:

scope that resumes objective tracking when closed

isObjectiveTrackingSuspended

public static boolean isObjectiveTrackingSuspended()

Check whether automatic objective tracking is suspended for the current thread.

Returns:

true if objective tracking is suspended, false otherwise

validate

public static <S extends Solution<S,I>, I extends Instance>
boolean validate(S solution)

getRandom

public static RandomGenerator getRandom()

isExecutionQueueAvailable

public static boolean isExecutionQueueAvailable()

submit

public static <T> Future<T> submit(Callable<T> task)

submit

public static <T> Future<T> submit(Runnable task,
 T value)

getMainObjective

public static <M extends Move<S,I>, S extends Solution<S,I>, I extends Instance>
Objective<M,S,I> getMainObjective()

getObjectives

public static <S extends Solution<S,I>, I extends Instance>
Map<String, Objective<?,S,I>> getObjectives()

getObjectivesW

public static Map<String, Objective<?,?,?>> getObjectivesW()

evalSolution

public static <S extends Solution<S,I>, I extends Instance>
Map<String,Double> evalSolution(S solution)

evalDeltas
