Returns: This builder for chaining.

Definition at line 1463 of file CpObjectiveProto.java.

◆ clearIntegerBeforeOffset()

Builder com.google.ortools.sat.CpObjectiveProto.Builder.clearIntegerBeforeOffset ( )

Internal fields to recover a bound on the original integer objective from
the presolved one. Basically, initially the integer objective fit on an
int64 and is in [Initial_lb, Initial_ub]. During presolve, we might change
the linear expression to have a new domain [Presolved_lb, Presolved_ub]
that will also always fit on an int64.

The two domain will always be linked with an affine transformation between
the two of the form:
old = (new + before_offset) * integer_scaling_factor + after_offset.
Note that we use both offsets to always be able to do the computation while
staying in the int64 domain. In particular, the after_offset will always
be in (-integer_scaling_factor, integer_scaling_factor).

int64 integer_before_offset = 7;

Returns: This builder for chaining.

Definition at line 1431 of file CpObjectiveProto.java.

◆ clearIntegerScalingFactor()

Returns: This builder for chaining.

Definition at line 1495 of file CpObjectiveProto.java.

◆ clearOffset()

Builder com.google.ortools.sat.CpObjectiveProto.Builder.clearOffset ( )

The displayed objective is always:
scaling_factor * (sum(coefficients[i] * objective_vars[i]) + offset).
This is needed to have a consistent objective after presolve or when
scaling a double problem to express it with integers.

Note that if scaling_factor is zero, then it is assumed to be 1, so that by
default these fields have no effect.

double offset = 2;

Returns: This builder for chaining.

Definition at line 1140 of file CpObjectiveProto.java.

◆ clearScalingFactor()

Builder com.google.ortools.sat.CpObjectiveProto.Builder.clearScalingFactor ( )

◆ clearScalingWasExact()
