Hello; I would like to use the function ga of the genetic algorithm toolbox toolbox , but my variables dont have lower an upper bounds, but each variable is include in data set (example: X1 takes values in {1,2,56,98}) How then can I include this information? Thanks
 

think about using the structure index to choose variables:

str={1,2,56,98}
bnd=length(str)

lower_bound=str(1)
upper_bound=str(bnd)

I wish it could help you!
 

Hello,
Thaks for you reply, but in your suggestion for example 3 is between lower_bound and lower_bound but it isn'y in str?
thanks
 

Hi lamlam,
My suggestion was as follow:

the lower_bound and upper_bound are respectively between 1 and length(str)
but you have to make a modification on selecting an element in this range in the way that you will work on str(selected_elt).

for exp:

str={1,2,56,98}
lower_bound=1
upper_bound=length(str)
%for the rest of your algorithm you have to modify all selected element (which are between lower and upper bound) and use it as an index for the str structure to get the corresponded element
str(slected_element)
%selected_elt is betwenn lower_bound and upper_bound.
I wish it could help you!

ps: can you please try to rely to this post about https://www.edaboard.com/threads/227798/ thank you!
Have a nice day!
