thanks for reply. I am talking about transformation matrix interface. LLL has transformation matrix interface: LLL(delta=None, eta=None, algorithm='fpLLL:wrapper', fp=None, prec=0, early_red=False, use_givens=False, use_siegel=False, transformation=False, **kwds) if set transformation=True, we have the output for transformation matrix.
However, BKZ does not have transformation matrix interface. BKZ(delta=None, algorithm='fpLLL', fp=None, block_size=10, prune=0, use_givens=False, precision=0, proof=None, **kwds) BKZ (sagemath.org) <https://doc.sagemath.org/html/en/reference/matrices/sage/matrix/matrix_integer_dense.html#sage.matrix.matrix_integer_dense.Matrix_integer_dense.BKZ> Though we can extract transformation matrix manually after computing BKZ result, it would be annoying. fplll have an interface for transformation matrix, so I think we had better use the interface (via fpylll). 2024年2月12日月曜日 10:50:58 UTC+9 Gareth Ma: Regarding fplll and flatter, Sage already has an interface with fplll (via fpylll), and issue #37207 is adding an interface call to flatter (the new pari implementation).

[background] I created Coppersmith small root method packages: kionactf/coppersmith(github.com) <https://github.com/kionactf/coppersmith> I am considering the package would be included in Sagemath tree. But I am not welcomed if my codes affect Sagemath devel. Actually, my codes depend on external packages(fplll, flatter). It might violate Sagemath philosophy: should not reinvent wheel. So I am starting to contribute Sagemath with a few related things. My code uses some transformation matrix interface for BKZ, so firstly I itry to add the feature on Sagemath code. [main issue] I want to add the feature that we can compute a transformation matrix on BKZ computation. If I want to use the recent merge on fpylll(add transformation interface to bkz_reduction #267 · fplll/fpylll (github.com) <https://github.com/fplll/fpylll/pull/267>) for adding the feature on Sagemath, how could we start? We need to wait next release on fpylll? --- Best regards, kiona -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
