Examples of solver.variables.RealVar.updateUpperBound()

solver.variables.RealVar.updateUpperBound()

Updates the upper bound of the domain of this to value. The instruction comes from propagator.

If value is greater than the upper bound of the domain, nothing is done and the return value is false,
if updating the upper bound to value leads to a dead-end (domain wipe-out), a ContradictionException is thrown,
otherwise, if updating the upper 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 upper bound (included) @param cause update releaser @return true if the upper bound has been updated, false otherwise @throws solver.exception.ContradictionException if the domain become empty due to this action

        if (objective.getSolver().getMeasures().getSolutionCount() > 0 && strict) {
          offset = precision;
        }
        RealVar io = (RealVar) objective;
        if (policy == ResolutionPolicy.MINIMIZE) {
          io.updateUpperBound(bestProvedUB.doubleValue() - offset, this);
          io.updateLowerBound(bestProvedLB.doubleValue(), this);
        } else {
          io.updateUpperBound(bestProvedUB.doubleValue(), this);
          io.updateLowerBound(bestProvedLB.doubleValue() + offset, this);
        }

        RealVar io = (RealVar) objective;
        if (policy == ResolutionPolicy.MINIMIZE) {
          io.updateUpperBound(bestProvedUB.doubleValue() - offset, this);
