[jgap-users] mixed-type chromosomes

[... ... <is...@ya...>]

Hi,

I was wondering whether a mixed-type chromosome is possible or has been implemented already.

Here is an example to illustrate what I mean:
you have to select the perfect person in terms of age/weight/sex given a fitness function.

In this case a mixed-type chromosome will consist of:
* an integer chromosome representing age,
* a float chromosome representing weight,
* a boolean chromosome representing sex.

genetic operations should recombine solutions (mixed-type chromosomes) but not mixing the sub-chromosomes.
the age-part chromosome should be recombined only with other age-part chromosomes etc.

any ideas or pointers to information?

thanking you in advance,

a.
