Bober's algorithm is completely different from descent.  It works with the L-function and its analytic properties which are partly conjectural.

thanks for your supporting and create this good program "pari/gp"

i also want to use conditionally upper bound algorithm written 

in https://arxiv.org/pdf/1112.1503.pdf

with pari if it is possible and i want to know that is somebody wrote it before or not? can i use it? cause i know it can be used in sage but the 'pari " program is much faster. this algorithm is written assuming truth of B.S.D and G.R.H

thanks
