Why this error "Too many input arguments" are shown in Optimization toolbox while using gamultiobj solver??

Hello, I am using optimization toolbox for solving a three objective constrained optimization model with the help of gamultiobj solver . There are 80 variables those includes 24 real valued and 56 binary variables. Also number of constraints are 60. I have prepared all the matrices for A, b, Aeq, beq, Lower bound and upper bound. After running the optimization, the toolbox shows "error running optimization too many input arguments". I am really frustrated and can't realize what to do now. Its really important for me to run the optimization. But, can't find any way. Anyone please suggest me what can I do now? It will be great help for me indeed.

Dear Hasan,

Have you tried the solution on this Mathworks Answers forum? (old version of MATLAB with new version Toolbox) If that doesn't work also try the solution, which is at this Mathworks Answers website.

Good luck! Christiaan

Unfortunately, gamultiobj does not handle integer constraints.

Is there any way you can convert your objective functions to linear functions? If so, you can use intlinprog to find the three absolute minima of the three objectives. That might be a good start.

Good luck,

Thanks Alan. I will try to follow your way. But, One thing to tell you that my three objective functions are linear and all the constraints are linear. Now, can you suggest any better idea? And another thing is intlinprog there in the optimization toolbox? I cant find it in the optimization toolbox of my matlab version of 2013. your help will highly be appreciated. if you want, I can provide you the code.

Sorry to say, but intlinprog was introduced in MATLAB R2014a.
