◆ getObjectiveOffset()

double Antares::Optimisation::LinearProblemMpsolverImpl::OrtoolsLinearProblem::getObjectiveOffset ( ) const

overridevirtual

Returns the current objective offset value.

Retrieves the constant term currently added to the objective function. For the Sirius solver, this value is stored locally; for other solvers, it uses OR-Tools' native support.

Returns: The current objective offset.

Implements Antares::Optimisation::LinearProblemApi::ILinearProblem.

◆ setObjectiveOffset()

void Antares::Optimisation::LinearProblemMpsolverImpl::OrtoolsLinearProblem::setObjectiveOffset ( double objectiveOffset )

overridevirtual

Sets the constant offset for the objective function.

The objective offset is a constant term added to the objective function. It shifts the objective value but does not affect the optimal solution. For the Sirius solver, this value is stored locally; for other solvers, it uses OR-Tools' native support.

Parameters

objectiveOffset The constant offset to add to the objective function.

Implements Antares::Optimisation::LinearProblemApi::ILinearProblem.

◆ solution()

OrtoolsMipSolution * Antares::Optimisation::LinearProblemMpsolverImpl::OrtoolsLinearProblem::solution ( bool verboseSolver )

Return the last solution or solve if no solution exist.

Parameters

verboseSolver

Returns: The solution
