How to solve optimization problem with discrete decision variable

hailiang shen — Fri, 19 Dec 2008 16:30:06 -0500

I am trying to solve an optimization problem with GA. And my decision variables are discrete, they are picked up from 50, 100, 150, 250, 350, 500.

Should I custom my population type?

Thanks for any help.
