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).

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.

Builder com.google.ortools.sat.ConstraintProto.Builder.clearIntDiv | ( | ) |
The int_div constraint forces the target to equal exprs[0] / exprs[1]. The division is "rounded" towards zero, so we can have for instance (2 = 12 / 5) or (-3 = -10 / 3). If you only want exact integer division, then you should use instead of t = a / b, the int_prod constraint a = b * t. If 0 belongs to the domain of exprs[1], then the model is deemed invalid.

Builder com.google.ortools.sat.ConstraintProto.Builder.clearIntProd | ( | ) |
The int_prod constraint forces the target to equal the product of all variables. By convention, because we can just remove term equal to one, the empty product forces the target to be one. Note that the solver checks for potential integer overflow. So the product of the maximum absolute value of all the terms (using the initial domain) should fit on an int64. Otherwise the model will be declared invalid.

The exactly_one constraint force exactly one literal to true and no more. Anytime a bool_or (it could have been called at_least_one) is included 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. This constraint does not support enforcement_literal. Just use a linear constraint if you need to enforce it.

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).
