clone

public static AllenIntervalNetworkSolver clone(AllenIntervalNetworkSolver oldSolver,
                                               Variable[] intervals,
                                               Constraint[] constraints,
                                               int newSize)

Creates a clone of an AllenIntervalNetworkSolver. This is done by copying the high level AllenIntervalConstraints, thus, care should be exercised when using this function together with createReducedCopy(org.metacsp.multi.allenInterval.AllenIntervalNetworkSolver, org.metacsp.multi.allenInterval.AllenInterval[]), since this function discards the high-level constraints (by translating them into SimpleDistanceConstraints).

Parameters:

oldSolver - the AllenIntervalNetworkSolver that should be cloned.

intervals - An array of AllenIntervals that should be re-mapped. The references to the in this array will be replaced with their corresponding AllenIntervals in the cloned AllenIntervalNetworkSolver. (All AllenIntervals in the old AllenIntervalNetworkSolver will be cloned regardless of the contents of this array.)

newSize - The new desired size of the network or 0 if the network should be minimized

Returns:

A new AllenIntervalNetworkSolver.

createReducedCopy

public static AllenIntervalNetworkSolver createReducedCopy(AllenIntervalNetworkSolver oldSolver,
                                                           AllenInterval[] intervals)

Creates a "reduced copy" of an AllenIntervalNetworkSolver. The reduced copy contains a subset of intervals from the original and their temporal properties are equivalent. The reduced copy does not contain the constraints from the original however, these are replaced with lower-level SimpleDistanceConstraints.

Parameters:

oldSolver - the solver that should be copied.

intervals - The intervals of interest in the old solver, each AllenInterval reference in this array will be replaced with a corresponding reference to its copy in the new AllenIntervalNetworkSolver.

Returns:

the copied AllenIntervalNetworkSolver.

createReducedCopy

public static AllenIntervalNetworkSolver createReducedCopy(AllenIntervalNetworkSolver oldSolver,
                                                           AllenInterval[] intervalsInOut,
                                                           int additionalCapactity)

Creates a "reduced copy" of an AllenIntervalNetworkSolver. The reduced copy contains a subset of intervals from the original and their temporal properties are equivalent. The reduced copy does not contain the constraints from the original however, these are replaced with lower-level SimpleDistanceConstraints.

Parameters:

oldSolver - the solver that should be copied.

intervalsInOut - The intervals of interest in the old solver, each AllenInterval reference in this array will be replaced with a corresponding reference to its copy in the new AllenIntervalNetworkSolver.

additionalCapactity - additional capacity for creating new intervals in the new solver.

Returns:

the copied AllenIntervalNetworkSolver.
