enum OsiIntParam |
OsiMaxNumIteration | The maximum number of iterations (whatever that means for the given solver) the solver can execute in the OsiSolverinterface::initialSolve() and the OsiSolverinterface::resolve() methods before terminating. |
OsiMaxNumIterationHotStart | The maximum number of iterations (whatever that means for the given solver) the solver can execute in the OsiSolverinterface::solveFromHotStart() method before terminating. |
OsiNameDiscipline |
The name discipline; specifies how the solver will handle row and column names.
|
OsiLastIntParam | Just a marker, so that OsiSolverInterface can allocate a static sized array to store parameters. |
Definition at line 7 of file OsiSolverParameters.hpp.
enum OsiDblParam |
OsiDualObjectiveLimit |
Dual objective limit.
This is to be used as a termination criteria in methods where the dual objective monotonically changes (e.g., dual simplex, the volume algorithm) |
OsiPrimalObjectiveLimit |
Primal objective limit.
This is to be used as a termination criteria in methods where the primal objective monotonically changes (e.g., primal simplex) |
OsiDualTolerance | The maximum amount the dual constraints can be violated and still be considered feasible. |
OsiPrimalTolerance | The maximum amount the primal constraints can be violated and still be considered feasible. |
OsiObjOffset | The value of any constant term in the objective function. |
OsiLastDblParam | Just a marker, so that OsiSolverInterface can allocate a static sized array to store parameters. |
Definition at line 40 of file OsiSolverParameters.hpp.
enum OsiStrParam |
OsiProbName |
Name of the problem.
This is the found on the Name card of an mps file. |
OsiSolverName |
Name of the solver.
This parameter is not settable. |
OsiLastStrParam | Just a marker, so that OsiSolverInterface can allocate a static sized array to store parameters. |
Definition at line 63 of file OsiSolverParameters.hpp.
enum OsiHintParam |
OsiDoPresolveInInitial | Whether to do a presolve in initialSolve. |
OsiDoDualInInitial |
Whether to use a dual algorithm in initialSolve.
The reverse is to use a primal algorithm |
OsiDoPresolveInResolve | Whether to do a presolve in resolve. |
OsiDoDualInResolve |
Whether to use a dual algorithm in resolve.
The reverse is to use a primal algorithm |
OsiDoScale | Whether to scale problem. |
OsiDoCrash | Whether to create a non-slack basis (only in initialSolve). |
OsiDoReducePrint | Whether to reduce amount of printout, e.g., for branch and cut. |
OsiDoInBranchAndCut | Whether we are in branch and cut - so can modify behavior. |
OsiLastHintParam | Just a marker, so that OsiSolverInterface can allocate a static sized array to store parameters. |
Definition at line 74 of file OsiSolverParameters.hpp.
enum OsiHintStrength |
OsiHintIgnore | Ignore hint (default). |
OsiHintTry | This means it is only a hint. |
OsiHintDo | This means do hint if at all possible. |
OsiForceDo | And this means throw an exception if not possible. |
