    • getEnforcementLiteralList

      public java.util.List<java.lang.Integer> getEnforcementLiteralList()
       The constraint will be enforced iff all literals listed here are true. If
 this is empty, then the constraint will always be enforced. An enforced
 constraint must be satisfied, and an un-enforced one will simply be
 ignored.
 This is also called half-reification. To have an equivalence between a
 literal and a constraint (full reification), one must add both a constraint
 (controlled by a literal l) and its negation (controlled by the negation of
 l).
 Important: as of September 2018, only a few constraint support enforcement:
 - bool_or, bool_and, linear: fully supported.
 - interval: only support a single enforcement literal.
 - other: no support (but can be added on a per-demand basis).
      repeated int32 enforcement_literal = 2;
      Specified by:
      getEnforcementLiteralList in interface ConstraintProtoOrBuilder
      Returns:
      A list containing the enforcementLiteral.

       The bool_and constraint forces all of the literals to be true.
 This is a "redundant" constraint in the sense that this can easily be

    • hasAtMostOne

      public boolean hasAtMostOne()
       The at_most_one constraint enforces that no more than one literal is
 true at the same time.
 Note that an at most one constraint of length n could be encoded with n
 bool_and constraint with n-1 term on the right hand side. So in a sense,
 this constraint contribute directly to the "implication-graph" or the
 2-SAT part of the model.
 This constraint does not support enforcement_literal. Just use a linear
 constraint if you need to enforce it. You also do not need to use it
 directly, we will extract it from the model in most situations.

    • hasExactlyOne

 into an at_most_one, then the bool_or is actually an exactly one
 constraint, and the extra literal in the at_most_one can be set to false.
 So in this sense, this constraint is not really needed. it is just here
 for a better description of the problem structure and to facilitate some
 algorithm.
