I'm currently working on PORTFOLIO Optimization for my research paper. I used GA to solve a multi-objective problem but instead of using binary number as a gene indicator/ chromosome I used real number. Then I normalized it for the weights to be equal to 1. Is it ok to use real numbers instead of binary numbers?
Having a real number for the chromosome would not be a problem. The input is not necessarily binary e.g. 8 queens problem.
Sure you can but some of the reproduction processes must be adjusted for this case. In binary you flip the 0 to 1 and vice versa in mutation but that is not the case in real numbers
You can use input with real numbers in AG. In some cases it is even preferable.

If you use real number you will get more search space as compared to the binary one.
please go through the my publication for more detail or use the Goldberg's book.
