Type Alias HighsModelStatus

Type Declaration

• "Not Set"

  No solve status has been established.

• "Load error"

  Input could not be loaded.

• "Model error"

  Model data is invalid.

• "Presolve error"

  Presolve failed.

• "Solve error"

  The selected solver failed.

• "Postsolve error"

  Mapping the presolved solution back failed.

• "Empty"

  The model has no rows or columns requiring optimization.

• "Optimal"

  An optimal solution was proved.

• "Infeasible"

  Infeasibility was proved.

• "Primal infeasible or unbounded"

  Presolve could not distinguish infeasibility from unboundedness.

• "Unbounded"

  Primal unboundedness was proved.

• "Bound on objective reached"

  The configured objective bound stopped the solve.

• "Target for objective reached"

  The configured MIP objective target was reached.

• "Time limit reached"

  The configured wall-clock limit stopped the solve.

• "Iteration limit reached"

  A solver iteration limit stopped the solve.

• "Unknown"

  HiGHS could not classify the final state.
