addAllEnforcementLiteral()

Builder com.google.ortools.sat.ConstraintProto.Builder.addAllEnforcementLiteral

(

java.lang.Iterable<? extends java.lang.Integer >

values

)

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;

Parameters

values

The enforcementLiteral to add.

Returns

This builder for chaining.

clearAllDiff()

Builder com.google.ortools.sat.ConstraintProto.Builder.clearAllDiff

(

)

The all_diff constraint forces all variables to take different values.

Definition at line 5144 of file ConstraintProto.java.

clearAtMostOne()

Builder com.google.ortools.sat.ConstraintProto.Builder.clearAtMostOne

(

)

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.

Definition at line 3429 of file ConstraintProto.java.

clearAutomaton()

Builder com.google.ortools.sat.ConstraintProto.Builder.clearAutomaton

(

)

The automaton constraint forces a sequence of variables to be accepted
by an automaton.

.operations_research.sat.AutomatonConstraintProto automaton = 17;

Definition at line 6067 of file ConstraintProto.java.

clearBoolAnd()

Builder com.google.ortools.sat.ConstraintProto.Builder.clearBoolAnd

(

)

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
encoded with many bool_or or at_most_one. It is just more space efficient
and handled slightly differently internally.

.operations_research.sat.BoolArgumentProto bool_and = 4;

Definition at line 3179 of file ConstraintProto.java.

clearBoolOr()

Builder com.google.ortools.sat.ConstraintProto.Builder.clearBoolOr

(

)

The bool_or constraint forces at least one literal to be true.

.operations_research.sat.BoolArgumentProto bool_or = 3;

Definition at line 2977 of file ConstraintProto.java.

clearBoolXor()

Builder com.google.ortools.sat.ConstraintProto.Builder.clearBoolXor

(

)

The bool_xor constraint forces an odd number of the literals to be true.

.operations_research.sat.BoolArgumentProto bool_xor = 5;

Definition at line 3914 of file ConstraintProto.java.

clearCircuit()

Builder com.google.ortools.sat.ConstraintProto.Builder.clearCircuit

(

)

The circuit constraint takes a graph and forces the arcs present
(with arc presence indicated by a literal) to form a unique cycle.

.operations_research.sat.CircuitConstraintProto circuit = 15;

Definition at line 5515 of file ConstraintProto.java.

clearConstraint()

(

)

Definition at line 2565 of file ConstraintProto.java.

clearCumulative()

Builder com.google.ortools.sat.ConstraintProto.Builder.clearCumulative

(

)

The cumulative constraint ensures that for any integer point, the sum
of the demands of the intervals containing that point does not exceed
the capacity.

.operations_research.sat.CumulativeConstraintProto cumulative = 22;

Definition at line 7204 of file ConstraintProto.java.

clearDummyConstraint()

Builder com.google.ortools.sat.ConstraintProto.Builder.clearDummyConstraint

(

)

This constraint is not meant to be used and will be rejected by the
solver. It is meant to mark variable when testing the presolve code.

.operations_research.sat.ListOfVariablesProto dummy_constraint = 30;

Definition at line 7394 of file ConstraintProto.java.

clearElement()

Builder com.google.ortools.sat.ConstraintProto.Builder.clearElement

(

)

The element constraint forces the variable with the given index
to be equal to the target.

.operations_research.sat.ElementConstraintProto element = 14;

Definition at line 5328 of file ConstraintProto.java.

clearEnforcementLiteral()

this is empty, then the constraint will always be enforced. An enforced

ignored.

This is also called half-reification. To have an equivalence between a

- 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;

Returns

This builder for chaining.

Definition at line 2862 of file ConstraintProto.java.

clearExactlyOne()

Builder com.google.ortools.sat.ConstraintProto.Builder.clearExactlyOne

(

)

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. You also do not need to use it
directly, we will extract it from the model in most situations.

.operations_research.sat.BoolArgumentProto exactly_one = 29;

Definition at line 3703 of file ConstraintProto.java.

clearIntDiv()

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.

.operations_research.sat.LinearArgumentProto int_div = 7;

Definition at line 4128 of file ConstraintProto.java.

clearInterval()

Builder com.google.ortools.sat.ConstraintProto.Builder.clearInterval

(

)

The interval constraint takes a start, end, and size, and forces
start + size == end.

.operations_research.sat.IntervalConstraintProto interval = 19;

Definition at line 6637 of file ConstraintProto.java.

clearIntMod()

Builder com.google.ortools.sat.ConstraintProto.Builder.clearIntMod

(

)

The int_mod constraint forces the target to equal exprs[0] % exprs[1].
The domain of exprs[1] must be strictly positive. The sign of the target
is the same as the sign of exprs[0].

.operations_research.sat.LinearArgumentProto int_mod = 8;

Definition at line 4336 of file ConstraintProto.java.

clearIntProd()

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.

.operations_research.sat.LinearArgumentProto int_prod = 11;

Definition at line 4562 of file ConstraintProto.java.

clearInverse()

Builder com.google.ortools.sat.ConstraintProto.Builder.clearInverse

(

)

The inverse constraint forces two arrays to be inverses of each other:
the values of one are the indices of the other, and vice versa.

.operations_research.sat.InverseConstraintProto inverse = 18;

Definition at line 6254 of file ConstraintProto.java.

clearLinear()

Builder com.google.ortools.sat.ConstraintProto.Builder.clearLinear

(

)

The linear constraint enforces a linear inequality among the variables,
such as 0 <= x + 2y <= 10.

.operations_research.sat.LinearConstraintProto linear = 12;

Definition at line 4963 of file ConstraintProto.java.

clearLinMax()

Builder com.google.ortools.sat.ConstraintProto.Builder.clearLinMax

(

)

The lin_max constraint forces the target to equal the maximum of all
linear expressions.
Note that this can model a minimum simply by negating all expressions.

.operations_research.sat.LinearArgumentProto lin_max = 27;

Definition at line 4773 of file ConstraintProto.java.

clearName()

Builder com.google.ortools.sat.ConstraintProto.Builder.clearName

(

)

For debug/logging only. Can be empty.

string name = 1;

Returns

This builder for chaining.

Definition at line 2641 of file ConstraintProto.java.

clearNoOverlap()

Builder com.google.ortools.sat.ConstraintProto.Builder.clearNoOverlap

(

)

The no_overlap constraint prevents a set of intervals from
overlapping; in scheduling, this is called a disjunctive
constraint.

.operations_research.sat.NoOverlapConstraintProto no_overlap = 20;

Definition at line 6830 of file ConstraintProto.java.

clearNoOverlap2D()

Builder com.google.ortools.sat.ConstraintProto.Builder.clearNoOverlap2D

(

)

The no_overlap_2d constraint prevents a set of boxes from overlapping.

.operations_research.sat.NoOverlap2DConstraintProto no_overlap_2d = 21;

Definition at line 7014 of file ConstraintProto.java.

clearReservoir()

Builder com.google.ortools.sat.ConstraintProto.Builder.clearReservoir

(

)

The reservoir constraint forces the sum of a set of active demands
to always be between a specified minimum and maximum value during
specific times.

.operations_research.sat.ReservoirConstraintProto reservoir = 24;

Definition at line 6447 of file ConstraintProto.java.

clearRoutes()

Builder com.google.ortools.sat.ConstraintProto.Builder.clearRoutes

(

)

The routes constraint implements the vehicle routing problem.

.operations_research.sat.RoutesConstraintProto routes = 23;

Definition at line 5696 of file ConstraintProto.java.

clearTable()

Builder com.google.ortools.sat.ConstraintProto.Builder.clearTable

(

)

The table constraint enforces what values a tuple of variables may
take.

.operations_research.sat.TableConstraintProto table = 16;

Definition at line 5880 of file ConstraintProto.java.

getAllDiff()

getAtMostOne()

com.google.ortools.sat.BoolArgumentProto com.google.ortools.sat.ConstraintProto.Builder.getAtMostOne

(

)

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,

The constraint will be enforced iff all literals listed here are true. If

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).

setEnforcementLiteral()

Builder com.google.ortools.sat.ConstraintProto.Builder.setEnforcementLiteral	(	int	index,

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).

index	The index to set the value at.
value	The enforcementLiteral to set.

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

So in this sense, this constraint is not really needed. it is just here

algorithm.
