Solver: Does not recognize unbounded model
Last modified: 2013-01-29 21:38:48 UTC
When the solver is not given any limiting conditions it does not recognize the situation as an unbounded model. Try this: (1) Enter the formula =A2*2 into cell A1 (2) Open the Solver dialog (Tools - Solver...) (3) Set "Target cell" to: $A$1 (4) Optimize result to: Maximum (5) Set "By changing cells" to: $A$2 (6) Click "Solve" Since the model is unbouded, Solver is supposed to show the "No Solution Feedback" with this message: "The modell is unbounded." But instead, Solver comes to a final result: 1.00E+030.
It's not the right way you used Solver. For this model y = 2x, there is just one y value to x value, so the maximum of the model is y value too. It has nothing to do with the model which is unbounded or not.
swubuntu, You're right. I misunderstand it. Li Meiying
