How to define discrete variables in GA

Hi

I need to optimize a function which has 8 variables by GA tool (genetic algorithm): beta(i) and psi(i) where i:1:4

How can i define discrete variables in GA (genetic algorithm).

I use GA tool.

Take a look at the Mixed Integer ga Optimization topic, and in particular the example Solving a Mixed Integer Engineering Design Problem Using the Genetic Algorithm, which shows how to use discrete non-integer variable constraints.
