In theory we could even have writen:

fncSelection = GenAlg::RouletteWheel<CGAController, unsigned long>;

but it is the same problem with MSVC6 that with the & form. If anyone has a
little time I would be interesting in understanding why MSVC6 doesn't accept

Unfortunately, just using &functionname doesnt work on template functions
( fncSelection = &GenAlg::RouletteWheel<CGAController, unsigned long>; )

I tried it and it gets confused about the template parameters
(thinks there are different possible functions)

boost::ptr_fun works fine though.. Thanx
I really could have used that function earlier on!

There's no need to use ptr_fun, either.

fncSelection = &GenAlg::RouletteWheel<CGAController, unsigned long>;
