Actually, the implementation also uses the trick described in "Solving
Thue equations without the full unit group", Math. Comp. (2000) in
order to avoid as much as possible calls to bnfcertify in large
degree.

The strategy is basically Baker's method as described in Tzanakis and
de Weger (JNT 1989) seminal paper, with significant algorithmic
improvements regarding the bound reduction and final enumeration
steps.

All the best, G.
