Detailed Description

Linear optimiser using the HiGHS mathematical library.

Constructor & Destructor Documentation

HighsOptimiser()

lucid::HighsOptimiser::HighsOptimiser ( std::map< std::string, std::string > options, std::string problem_log_file = "", std::string iis_log_file = "" )

explicit

Construct a new Highs Optimiser object.

Parameters

options	map of options to set in the HiGHS solver
problem_log_file	file to log the problem to. If empty, no logging is done
iis_log_file	file to log the irreducible infeasible set (IIS) to, if found. If empty, no logging is done

Member Function Documentation

Optimiser()

lucid::Optimiser::Optimiser ( std::string problem_log_file = "", std::string iis_log_file = "" )

explicit

Construct a new Optimiser object.

If problem_log_file is provided, the optimiser will log the LP problem to the specified file. If iis_log_file is provided, the optimiser will log the Irreducible Inconsistent Subsystem (IIS) to the specified file if the problem is found to be infeasible.

Parameters

problem_log_file	file to log the problem to
iis_log_file	file to log the IIS to

solve_fourier_barrier_synthesis_impl()

bool lucid::HighsOptimiser::solve_fourier_barrier_synthesis_impl ( const FourierBarrierSynthesisProblem & params, const SolutionCallback & cb ) const

overrideprivatevirtual

Implementation of the Fourier barrier synthesis solver.

It interfaces with the specific LP solver backend. See FourierBarrierCertificate::synthesize for more details.

Parameters

params	problem definition
cb	callback function called when the optimisation is done

Returns

true if the optimisation was successful

false if no solution was found (i.e., the problem is infeasible

Implements lucid::Optimiser.

to_string()

std::string lucid::HighsOptimiser::to_string ( ) const

nodiscardoverridevirtual

Obtain the string representation of this object.

Returns

string representation of this object

Reimplemented from lucid::Optimiser.
