- Which of the following is true? 1.Multistart feature in Solver guarantees that the solution obtained from Solver is a global optimal solution. 2.A nonlinear optimization problem can have multiple global optimal solutions. 3.A local optimum for an optimization problem is the best point in the feasible region. 4.There is no guarantee that a solution of a linear programming model obtained from Solver is a global solution.Which of the following statements is not true? Group of answer choices An transshipment problem is a special case of a transportation problem in which all supplies and all demands are equal to 1. Transshipment problems can also be solved by general purpose linear programming codes. Transshipment problems are transportation problems in which a shipment may move through intermediate nodes before reaching a particular destination node. Transshipment problems can be converted to larger transportation problems and solved by a special transportation program.Which of the following statements about linear programming is NOT correct? A. Minimization problems are often unbounded inward. B. The iso-cost approach attempts to move the objective function in towards the origin as far as possible. C. The feasible region is determined the same way for a minimization problem as for a maximization problem. D. LP problems can be structured to minimize costs as well as maximize profits. (Don't hand writing solution)
