available that provides the
basic framework of a GA/SA into which I could basically plug an

It seems that R itself does not do this - is there any code/package
which would let me do something like this?

Hi,
I'm using a package that has a number of formats. I have C code to
parse these formats the results of which are generally integer arrays.
