java.lang.Objectqs.QS
QS is a wrapper class for a collection of constants used in Problem methods.
MAX_DOUBLE is used when setting the lower and upper bounds of a variable to indicate infinity.
MIN,MAX are used when changing the objective sense
The constants NO_STATUS, LP_OPTIMAL, LP_PRIMAL_FEASIBLE, LP_PRIMAL_INFEASIBLE, LP_PRIMAL_UNBOUNDED, LP_DUAL_FEASIBLE, LP_DUAL_INFEASIBLE, LP_DUAL_UNBOUNDED, and LP_UNSOLVED are used to indicate a Problem's status, that isThe constants PARAM_PRIMAL_PRICING_I, PARAM_PRIMAL_PRICING_II, PARAM_DUAL_PRICING_I, PARAM_DUAL_PRICING_II, PARAM_SIMPLEX_DISPLAY, and PARAM_SIMPLEX_MAX_ITERATIONS together with the constants PRIMAL_DEVEX, PRIMAL_STEEP, PRIMAL_PARTIAL, PRIMAL_PROJECT, PRIMAL_DANTZIG, DUAL_DANTZIG, DUAL_STEEP, DUAL_PARTIAL are used to by the set_param method of the Problem class to indicate which pricing strategy the simplex optimizer should employ in its two phases.
