Protected Member Functions
void	terminate (const std::string &location, const std::string &message) const
	Interrupt the program and output current merged .lp and .mps files.

void	export_problem (const std::string &filename="log_merged", bool export_lp=false) const
	Export problem into INPUTROOT/filename and optionally writes the lp variant We do it this way because we cannot read a master problem not at the input root.

	Creates a local solver from a MPS file.

	Weights local solver's objective function by a given value.

VariableMap	merge_local_solver (SolverAbstract &local_solver, const std::string &local_prefix, const VariableMap &local_var_map, const std::string &filename) const

◆ get_local_solver()

std::shared_ptr< SolverAbstract > AbstractMergeMPS::get_local_solver	(	const std::filesystem::path &	root_dir,

nodiscardprotected

Creates a local solver from a MPS file.

Parameters

root_dir	: Directory of MPS file
filename	: MPS file name

Limitation: on windows may not support master problem with full path as name

virtual void AbstractMergeMPS::launch ( )

pure virtual

		const std::string &	filename ) const

protected

Merges local to global solver.

Parameters

local_solver	: Local solver

filename	: MPS file name

void AbstractMergeMPS::multiply_obj_by_weight_factor	(	SolverAbstract &	local_solver,
		double	weight ) const

protected

Weights local solver's objective function by a given value.

Parameters
