setting-up input variable in genetic algorithm
显示 更早的评论
How can I set up an input variable in my ga that varies from 1 to 2 with steps of 0,1?
The results of my ga has too many significant digits after comma ( precisely 4).
Thank you

If you are seeing exactly 4 significant digits, chances are that you have
format short
in effect, and that you would see more digits if you used
format long g

- 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
below is the link to see how we can pass extra paramters for customization of ga function
hope it helps,
thanks
