Maximize the objective.
Constants defining the problem status.
Unknown problem status.
The problem is primal and dual feasible.
The problem is at least primal feasible.
The problem is at least least dual feasible.
The problem is primal infeasible.
The problem is dual infeasible.
The problem is primal and dual infeasible.
The problem is illposed.
The problem is primal infeasible or unbounded.
Defines properties of either a primal or a dual solution. A model may contain multiple solutions which may have different status. Specifically, there will be individual solutions, and thus solution statuses, for the interior-point, simplex and integer solvers.
Undefined solution. This means that no values exist for the relevant solution.
The solution status is unknown; this will happen if the user inputs values or a solution is read from a file or the solver stalled.
The solution values are feasible and optimal.
The solution is feasible.
The solution is a certificate of infeasibility.
The solution is a certificate of illposedness.
Used when requesting a specific solution from a
Auto-select the default solution; usually this will be the integer solution, if available, otherwise the basic solution, if available, otherwise the interior-point solution.
Select the basic solution.
Select the interior-point solution.
Select the integer solution.
Constants used for reporting solver status from
An error occurred.
The model was not solved because it lost the race.
