Arguments

• solver, object, x: A ConstantSolver object.
• problem: A Problem object.
• solution: A Solution object to invert.
• inverse_data: A list containing data necessary for the inversion.
• data: Data for the solver.
• 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(ConstantSolver): Can the solver handle mixed-integer programs?
• accepts(object = ConstantSolver, problem = Problem): Is the solver capable of solving the problem?
• perform(object = ConstantSolver, problem = Problem): Returns a list of the ConstantSolver, Problem, and an empty list.
• invert(object = ConstantSolver, solution = Solution, inverse_data =list): Returns the solution.
• name(ConstantSolver): Returns the name of the solver.
• import_solver(ConstantSolver): Imports the solver.
• is_installed(ConstantSolver): Is the solver installed?
• solve_via_data(ConstantSolver): Solve a problem represented by data returned from apply.
• reduction_solve(object = ConstantSolver, problem = ANY): Solve the problem and return a Solution object.
