C++ Reference: class GreaterThanAtLeastOneOfPropagator
This documentation is automatically generated.If we have:
- selectors[i] => (target_var >= vars[i] + offset[i])
- and we known that at least one selectors[i] must be true
then we can propagate the fact that if no selectors is chosen yet, the lower bound of target_var is greater than the min of the still possible alternatives.
This constraint take care of this case when no selectors[i] is chosen yet.
This constraint support duplicate selectors.
