I am working on minimizing a multiple function of variables using genetic algorithm (gamultiobj).

My problem is how I can mix integer, real and binary number using the Multiobjective Genetic Toolbox Solver: gamultiobj.

I know this link and just wonder I can mix them together!

Thank for helping,

Fakher.

Fakher,
Unfortunately, there is no direct way to do that with gamultiobj solver. You can write your custom population creation, crossover, and mutation operators to work with integer, real, and binary numbers. Look in the doc for how to write custom population. Look at the demo section for one such example of integer population to get started and look at this example:

Thank you,

Is it possible to use gamultiobj solver with only integer variable for constrained functions (with linear inequalities and equalities )?
