Arguments

• solver, object, x: A GLPK object.
• status: A status code returned by the solver.
• solution: The raw solution returned by the solver.
• inverse_data: A list containing data necessary for the inversion.
• data: Data generated via an apply call.
• warm_start: A boolean of whether to warm start the solver.
• verbose: A boolean of whether to enable solver verbosity.
• feastol: The feasible tolerance.
• reltol: The relative tolerance.
• abstol: The absolute tolerance.
• num_iter: The maximum number of iterations.
• solver_opts: A list of Solver specific options
• solver_cache: Cache for the solver.

Methods (by generic)

• mip_capable(GLPK): Can the solver handle mixed-integer programs?
• status_map(GLPK): Converts status returned by the GLPK solver to its respective CVXPY status.
• name(GLPK): Returns the name of the solver.
• import_solver(GLPK): Imports the solver.
• invert(object = GLPK, solution = list, inverse_data = list): Returns the solution to the original problem given the inverse_data.
• solve_via_data(GLPK): Solve a problem represented by data returned from apply.
