I tried to solve a problem that the objective is to find maximize value from X1, X2, and X3 and should be in integer. So, I use the intlinprog in Matlab to find the maximize value. Since I looking for maximize, I change "f" to "-f" and the result is negative number with the result 0 X1, 4 X2, and 2 X3. Attached below :
In confused why the result is negative. Then, I tried to solve the problem using Excel Solver (maximize) and I got a reasonable result below :
The confused things is, when I set the Excel Solver to minimize and also I remove "-" in Matlab (from "-f" to "f", the result will be same between the Excel Solver and Intlinprog Matlab.
Anyone here can help me, how to solve this problem ? How to use maximize function in intlinprog properly?
Thank you for your kindly help.
