Hi,
I am a student very new to Matlab. I am trying to use the GATool (OptimTool) to solve the assignment problem (assignment 1 person to 1 machine). I would like to know how to write the fitness function and how to enter the constraints in the tool.
Min Z= 14X11 +5X21 +8X31 +7X41 +2X12 +12X22 +6X23 +5X24 +7X31 +8X32 +3X33 +9X34 +2X341 +4X42 +6X43 +10X44.
Subject to: X11+X21+X31+X41=1 X12+X22+X32+X42=1 X13+X23+X33+X43=1 X14+X24+X34+X44=1 X11+X12+X13+X14=1 X21+X22+X23+X24=1 X31+X32+X33+X34=1 X41+X42+X43+X44=1 All variables=0 or 1.
Thank you.

I too need the answer for this question.@Rameza if you know means pls share the code.

@buvaneshwari tk, Is the Genetic Algorithm (GA) the optimization method allowed to use? Are there any benefits of using GA to solve your linear programming problem?
Can continue the discussion here in a meaningful way. If the LP problem is too large, then illustrate a simple toy problem for your case. Don't straightaway jump into the larger problem without understanding how to solve it in the first place.

More importantly, can you clarify if your are integer variables, or continuous variable, or a mixed of both? This determine which algorithm is more suitable for solving your linear programming problem.
