Yes, Brent-Dekker is well known. There are good descriptions all
around. Actually, Wikipedia's [0] is pretty well written and
accessible. It has also hints on the improvements usual nowadays.

Actually, AFAICS, GSL (the GNU scientific library) [1] implements
its one-dimensional root finding [2] based on Brent-Dekker.

Cheers
