- Well if you actually had a complete GFNS implementation for
- general numbers I believe you would obtain more reliable estimates by
- performing a whole bunch of "wimpy" factorizations as opposed to a
- single factorization of RSA-129.
- You might also have a reliable figure of merit for what con-
- stitutes a good polynomial representation. Extensive searches for
- polynomials using different criteria than the ones you will eventually
- use to select a polynomial (which you are encouraging people to per-
- form) are a waste of computer time (since such searches are inherant-
- ly inefficient).
