What are the different meanings of the model statuses?

Processing Statuses

Models go through different steps while being processed.

Queued

The model is waiting for other internal processes to finish before starting solving.

Solving

The model is being processed and the Rose solver is working on a solution

Completed Statuses

Once a problem has finished solving, several outcomes are possible.

Optimal

The model has been solved to optimality, within the defined tolerances. The optimal solution, which meets all specified constraints and achieves the best possible objective value, is available for download. To change or view the tolerances, see this article for how to How to change and view the solver parameters.

Feasible

The Rose solver found a feasible solution but was interrupted by one of the stopping criteria before it could find the optimal solution. To change or view the stopping criteria, see this article for how to How to change and view the solver parameters.

Cancelled

A user has manually stopped the solver during a run.

Unbounded

The model has been determined to be unbounded, meaning that the objective function can improve indefinitely without violating any constraints. In other words, the objective value is positive infinity for a maximization problem and negative infinity for a minimization problem. This means that at least one of the decision values is going to either positive or negative infinity. In such cases, no finite optimal solution exists, and the model's formulation may need to be reviewed.

Note that this model may still have a feasible solution. If you want to see if a feasible solution exists, set the objective value to zero and resubmit the problem.

Infeasible

The model is deemed infeasible when no solution exists that satisfies all of the imposed constraints. This means that there is no possible combination of values for the decision variables that can meet the requirements set by the constraints, and therefore, no valid solution exists.

Error

An unexpected issue occurred somewhere in the process. This error may result from incorrect input data, a misconfiguration in the model settings, or an internal problem within the solver. Please review your inputs and settings, and if the problem persists, please let us know about it, we can help. Clicking "show more" on the model solution page will also open the drawer and show the specific error message. Please provide this error message upon reaching out for support.
