Solver Process

• Does the solver minimize or maximize by default?
• Is Rose deterministic?
• How is the optimality gap, or MIP gap, calculated?
• How Rose handles large and small numbers, special cases for infinity and zero
• Why does the objective function value sometimes not match the best objective?
