Internal field. Do not set. When we scale a FloatObjectiveProto to a

integer version, we set this to true if the scaling was exact (i.e. all

original coeff were integer for instance).

Internal field. This is only useful for inner_objective_lower_bound, It
|
|
should never be set in most cases, so we have the simple:
|
|
sum(coefficients[i] * objective_vars[i]) >= inner_objective_lower_bound.
|
|
This is similar to offset/scaling_factor but allows to stay in the integer
|
|
domain. Note that the formula is not the same than for the floating point
|
|
objective. If this is set, we have
|
|
linear_expression * scaling + offset >= inner_objective_lower_bound
