setting-up input variable in genetic algorithm

Internally to your objective function, change your integer variable x to x/10. Or,
Make a list of allowable values in a variable indexvar. Have your objective function evaluate indexvar(x), where x is your integer-valued variable. This is more flexible, in that you can have any list of allowable values.

See Solving a Mixed Integer Engineering Design Problem Using the Genetic Algorithm and in particular the section Add Discrete Non-Integer Variable Constraints.

Hi,

You can try using optimoptions for genetic algorithm where you can many options for passing extra parameters either in form of variables or a user defined function.

please refer the below link for more information on optimoptions for ga function

https://www.mathworks.com/help/gads/genetic-algorithm-options.html

below is the link to see how we can pass extra paramters for customization of ga function

hope it helps,

thanks
