List of updateLowerBound() Examples

Examples of updateLowerBound()

solver.explanations.antidom.AntiDomInterval.updateLowerBound()
solver.explanations.antidom.AntiDomain.updateLowerBound()
Update the lower bound @param oldLB the old lower bound value @param newLB the new lower bound value
solver.variables.IntVar.updateLowerBound()
Updates the lower bound of the domain of this to value. The instruction comes from propagator.
- If value is smaller than the lower bound of the domain, nothing is done and the return value is false,
- if updating the lower bound to value leads to a dead-end (domain wipe-out), a ContradictionException is thrown,
- otherwise, if updating the lower bound to value can be done safely, the event type is created (the original event can be promoted) and observers are notified and the return value is true
@param value new lower bound (included) @param cause updating releaser @return true if the lower bound has been updated, false otherwise @throws ContradictionException if the domain become empty due to this action
solver.variables.RealVar.updateLowerBound()
Updates the lower bound of the domain of this to value. The instruction comes from propagator.
- If value is smaller than the lower bound of the domain, nothing is done and the return value is false,
- if updating the lower bound to value leads to a dead-end (domain wipe-out), a ContradictionException is thrown,
- otherwise, if updating the lower bound to value can be done safely, the event type is created (the original event can be promoted) and observers are notified and the return value is true
@param value new lower bound (included) @param cause updating releaser @return true if the lower bound has been updated, false otherwise @throws ContradictionException if the domain become empty due to this action
