I believe that vectors of integers or floating point numbers have been
used many times, even though Holland's original idea was to use bit
strings.

My work (available via URL below) uses floating point arrays as the
"chromosomes".  Selection, crossover and mutation are performed.  It is
extensively documented, both in text files and comments in the C code.
(and even some diagrams!)

I suggest the 4play package as having the most complete documentation.
