True/False: Answer the following questions. 2 A solution is "optimal", if in addition to being infeasible, it yields the best (maximum or minimum) value of the constraint. * False O True Basic solutions in the simplex method refer to "all feasible points" in the graphical solution space True False The design of the simplex method allows simultaneous increases in variables * False True Decisional variables are unknown and controllable parameters of the system which finding their value is the purpose of the problem-solving effort. * O False True Constraints are the restrictions that the solution must satisfy. * False True
