For me that's not completely off-topic as I always wished boost could 
provide this algorithms one day :-) However, I'm not really an expert in 
this field so I never started working on it.

Nevertheless, there is an earlier paper by David Gay from 1990 for which 
an implementation exists. AFAIK Mozilla's JavaScript implementation also 
uses a java port of it. Although I have downloaded Burger's paper 
(published in 1996, IIRC) once, I never investigated what's 
different/improved there.

Gay's implementation can be found both at
http://www.netlib.org/fp/index.html
and
http://citeseer.nj.nec.com/gay90correctly.html
(seems to be down at the moment).

If you also need the papers, tell me and I send them offlist.
