flixopt.solvers

This module contains the solvers of the flixopt framework, making them available to the end user in a compact way.

Classes

GurobiSolver dataclass

GurobiSolver(mip_gap: float, time_limit_seconds: int, extra_options: Dict[str, Any] = dict())

Bases: _Solver

Parameters:

Name	Type	Description	Default
mip_gap	float	Solver's mip gap setting. The MIP gap describes the accepted (MILP) objective, and the lower bound, which is the theoretically optimal solution (LP)	required
time_limit_seconds	int	Solver's time limit in seconds.	required
extra_options	str	Filename for saving the solver log.	dict()

Attributes

options property

options: Dict[str, Any]

Return a dictionary of solver options.

HighsSolver dataclass

HighsSolver(mip_gap: float, time_limit_seconds: int, extra_options: Dict[str, Any] = dict())

Bases: _Solver

Parameters:

Name	Type	Description	Default
mip_gap	float	Solver's mip gap setting. The MIP gap describes the accepted (MILP) objective, and the lower bound, which is the theoretically optimal solution (LP)	required
time_limit_seconds	int	Solver's time limit in seconds.	required
threads	int	Number of threads to use.	required
extra_options	str	Filename for saving the solver log.	dict()

Attributes

options property

options: Dict[str, Any]

Return a dictionary of solver options.
