◆ getAbsoluteGapLimit()

double com.google.ortools.sat.SatParameters.getAbsoluteGapLimit ( )
Stop the search when the gap between the best feasible objective (O) and
our best objective bound (B) is smaller than a limit.
The exact definition is:
- Absolute: abs(O - B)
- Relative: abs(O - B) / max(1, abs(O)).

Important: The relative gap depends on the objective offset! If you
artificially shift the objective, you will get widely different value of
the relative gap.

Note that if the gap is reached, the search status will be OPTIMAL. But
one can check the best objective bound to see the actual gap.

If the objective is integer, then any absolute gap < 1 will lead to a true
optimal. If the objective is floating point, a gap of zero make little
sense so is is why we use a non-zero default value. At the end of the
search, we will display a warning if OPTIMAL is reported yet the gap is
greater than this absolute gap.

optional double absolute_gap_limit = 159 [default = 0.0001];

Returns
The absoluteGapLimit.

boolean com.google.ortools.sat.SatParameters.getAddLpConstraintsLazily ( )
If true, we start by an empty LP, and only add constraints not satisfied
by the current LP solution batch by batch. A constraint that is only added
like this is known as a "lazy" constraint in the literature, except that we
currently consider all constraints as lazy here.

◆ getAddObjectiveCut()

boolean com.google.ortools.sat.SatParameters.getAddObjectiveCut ( )
When the LP objective is fractional, do we add the cut that forces the
linear objective expression to be greater or equal to this fractional value
rounded up? We can always do that since our objective is integer, and
combined with MIR heuristic to reduce the coefficient of such cut, it can
help.

variable demands.

WARNING: with this encoding, the constraint takes a slightly different
meaning. There must exist a permutation of the events occurring at the same
time such that the level is within the reservoir after each of these events
(in this permuted order). So we cannot have +100 and -100 at the same time
if the level must be between 0 and 10 (as authorized by the reservoir
constraint).

When scaling constraint with double coefficients to integer coefficients,

the lowest power such that we have no potential overflow (see
mip_max_activity_exponent) and the worst case constraint activity error
does not exceed this threshold.

Note that we also detect constraint with rational coefficients and scale
them accordingly when it seems better instead of using a power of 2.

We also relax all constraint bounds by this absolute value. For pure
integer constraint, if this value if lower than one, this will not change
anything. However it is needed when scaling MIP problems.

If we manage to scale a constraint correctly, the maximum error we can make
will be twice this value (once for the scaling error and once for the
relaxed bounds). If we are not able to scale that well, we will display
that fact but still scale as best as we can.

When this is true, the cumulative constraint is reinforced with overload
checking, i.e., an additional level of reasoning based on energy. This
additional level supplements the default level of reasoning as well as
timetable edge finding.

This always result in better propagation, but it is usually slow, so
depending on the problem, turning this off may lead to a faster solution.

◆ getUsePrecedencesInDisjunctiveConstraint()

boolean com.google.ortools.sat.SatParameters.getUsePrecedencesInDisjunctiveConstraint ( )
When this is true, then a disjunctive constraint will try to use the
precedence relations between time intervals to propagate their bounds
further. For instance if task A and B are both before C and task A and B
are in disjunction, then we can deduce that task C must start after
duration(A) + duration(B) instead of simply max(duration(A), duration(B)),
provided that the start time for all task was currently zero.

This always result in better propagation, but it is usually slow, so
depending on the problem, turning this off may lead to a faster solution.

◆ getVariableActivityDecay()

double com.google.ortools.sat.SatParameters.getVariableActivityDecay ( )
Each time a conflict is found, the activities of some variables are
increased by one. Then, the activity of all variables are multiplied by
variable_activity_decay.

To implement this efficiently, the activity of all the variables is not
decayed at each conflict. Instead, the activity increment is multiplied by
1 / decay. When an activity reach max_variable_activity_value, all the

◆ hasAbsoluteGapLimit()

boolean com.google.ortools.sat.SatParameters.hasAbsoluteGapLimit ( )
Stop the search when the gap between the best feasible objective (O) and
our best objective bound (B) is smaller than a limit.
The exact definition is:
- Absolute: abs(O - B)
- Relative: abs(O - B) / max(1, abs(O)).

Important: The relative gap depends on the objective offset! If you
artificially shift the objective, you will get widely different value of
the relative gap.

Note that if the gap is reached, the search status will be OPTIMAL. But
one can check the best objective bound to see the actual gap.

If the objective is integer, then any absolute gap < 1 will lead to a true
optimal. If the objective is floating point, a gap of zero make little
sense so is is why we use a non-zero default value. At the end of the
search, we will display a warning if OPTIMAL is reported yet the gap is
greater than this absolute gap.

variable demands.

WARNING: with this encoding, the constraint takes a slightly different
meaning. There must exist a permutation of the events occurring at the same
time such that the level is within the reservoir after each of these events
(in this permuted order). So we cannot have +100 and -100 at the same time
if the level must be between 0 and 10 (as authorized by the reservoir
constraint).

boolean com.google.ortools.sat.SatParameters.hasMipWantedPrecision ( )
When scaling constraint with double coefficients to integer coefficients,
we will multiply by a power of 2 and round the coefficients. We will choose
the lowest power such that we have no potential overflow (see
mip_max_activity_exponent) and the worst case constraint activity error
does not exceed this threshold.

Note that we also detect constraint with rational coefficients and scale
them accordingly when it seems better instead of using a power of 2.

We also relax all constraint bounds by this absolute value. For pure
integer constraint, if this value if lower than one, this will not change
anything. However it is needed when scaling MIP problems.

If we manage to scale a constraint correctly, the maximum error we can make
will be twice this value (once for the scaling error and once for the
relaxed bounds). If we are not able to scale that well, we will display
that fact but still scale as best as we can.

- Box 2 is after Box 1 on x.
- Box 1 is after Box 2 on x.
- Box 2 is after Box 1 on y.

Note that 'num_workers' is the preferred name, but if it is set to zero,
we will still read the deprecated 'num_search_workers'.

This parameters is here to prevent user to think the solution is optimal
when it might not be. One will need to manually set this to false to solve
a MIP model where the optimal might be different.

boolean com.google.ortools.sat.SatParameters.hasUseOverloadCheckerInCumulative ( )
When this is true, the cumulative constraint is reinforced with overload
checking, i.e., an additional level of reasoning based on energy. This
additional level supplements the default level of reasoning as well as
timetable edge finding.

This always result in better propagation, but it is usually slow, so
depending on the problem, turning this off may lead to a faster solution.

optional bool use_overload_checker_in_cumulative = 78 [default = false];

Returns
Whether the useOverloadCheckerInCumulative field is set.

◆ hasUsePhaseSaving()

boolean com.google.ortools.sat.SatParameters.hasUsePhaseSaving ( )
If this is true, then the polarity of a variable will be the last value it
was assigned to, or its default polarity if it was never assigned since the
call to ResetDecisionHeuristic().

Actually, we use a newer version where we follow the last value in the
longest non-conflicting partial assignment in the current phase.

This is called 'literal phase saving'. For details see 'A Lightweight
Component Caching Scheme for Satisfiability Solvers' K. Pipatsrisawat and
A.Darwiche, In 10th International Conference on Theory and Applications of
Satisfiability Testing, 2007.

◆ hasUsePrecedencesInDisjunctiveConstraint()

boolean com.google.ortools.sat.SatParameters.hasUsePrecedencesInDisjunctiveConstraint ( )
When this is true, then a disjunctive constraint will try to use the
precedence relations between time intervals to propagate their bounds
further. For instance if task A and B are both before C and task A and B
are in disjunction, then we can deduce that task C must start after
duration(A) + duration(B) instead of simply max(duration(A), duration(B)),
provided that the start time for all task was currently zero.

This always result in better propagation, but it is usually slow, so
depending on the problem, turning this off may lead to a faster solution.

boolean com.google.ortools.sat.SatParameters.hasUseSymmetryInLp ( )
When we have symmetry, it is possible to "fold" all variables from the same
orbit into a single variable, while having the same power of LP relaxation.
This can help significantly on symmetric problem. However there is
currently a bit of overhead as the rest of the solver need to do some
translation between the folded LP and the rest of the problem.

boolean com.google.ortools.sat.SatParameters.hasUseTimetablingInNoOverlap2D ( )
When this is true, the no_overlap_2d constraint is reinforced with
propagators from the cumulative constraints. It consists of ignoring the
position of rectangles in one position and projecting the no_overlap_2d on
the other dimension to create a cumulative constraint. This is done on both
axis. This additional level supplements the default level of reasoning.

◆ hasVariableActivityDecay()

boolean com.google.ortools.sat.SatParameters.hasVariableActivityDecay ( )
Each time a conflict is found, the activities of some variables are
increased by one. Then, the activity of all variables are multiplied by
variable_activity_decay.

To implement this efficiently, the activity of all the variables is not
decayed at each conflict. Instead, the activity increment is multiplied by
1 / decay. When an activity reach max_variable_activity_value, all the
activity are multiplied by 1 / max_variable_activity_value.
