Hello,
How can i do a multiobjective GA optimization with integer variables constraint.
I usedThe GAMULTIOBJ, but it does not work for integer variables.
Thank you

Sorry, currently there is no built-in function to perform integer-constrained multiobjective optimization.

Hello,
is this fixed in the mean time? On the documentation page it is written integer variables can be used for multiobjective GA. Find Pareto front of multiple fitness functions using genetic algorithm - MATLAB gamultiobj - MathWorks Deutschland
The example in Live-Editor works fine but the same example does not work on my version in Matlab (R2020b). Is this available for later versions only?
Thank you

To find out, consult the Release Notes. There you see that integer constraints were first supported in gamultiobj in R2021b.

Hello all,
Thank your for your continuous help and assistance.
I have a problem while running GAMULTIOBJ with integer variables. I set the population size and number of generations to 50. Consequently when generation terminated and plotting the pareto front, I got oniy 18 points where all of them are duplicated and some others should be omitted if GAMULTIOBJ is working properly.
Kindly find attached the results which i got. Thank you

This looks like a new question to me. I suggest that you repost this question as a new question so that people can see it and possibly answer it.

I have the same above question?
Hello,
How can i do a Multiobjective GA optimization with binary variables constraint.
How can i get correct code of the multiobjective GA optimization with integer variables?.
I want your comment.

Meanwhile, you can consult the Release Notes for R2021b.
