fplll 5.1 and fpylll 0.2.4dev

New versions of fplll and fpylll were released today. I’ve reproduced release notes below for greater visibility. The biggest user-visible changes for fplll are probably that

• CVP enumeration is not experimental any more,
• support for external enumeration libraries (go write that GPU implementation of enumeration) was added and
• support for OSX was greatly improved.

On the fpylll side, the biggest user-visible changes are probably various API updates and a much nicer strategy/framework for gathering statistics about BKZ.

The next version of fplll will contain support for LLL reduction on Gram matrices.

Release Notes

Fplll

Hi there,

fplll 5.1.0 was released on 26 March 2017 and is available at

https://github.com/fplll/fplll/releases/tag/5.1.0

Major changes in fplll-5.1.0 compared to fplll-5.0.3:

• CVP is not experimental any longer by implementing the resetting feature (Guillaume Bonnoron https://github.com/fplll/fplll/pull/191)
• pruner rewrite providing faster pruning, a new greedy pruning strategy, support for multiple solutions and a simpler API (Léo Ducas https://github.com/fplll/fplll/pull/228)
• support for external enumeration libraries paving the way for multithreaded/MPI/GPU enumeration libraries. See https://github.com/cr-marcstevens/fplll-extenum for an example external library (Marc Stevens https://github.com/fplll/fplll/pull/227)
• Gaussian Heuristic improved and renamed to ‘adjust\_radius\_to\_gh\_bound‘ (Léo Ducas https://github.com/fplll/fplll/pull/231)
• Reduced calls to LLL during BKZ (Martin Albrecht https://github.com/fplll/fplll/pull/226, Damien Stehlé and Shi Bai https://github.com/fplll/fplll/pull/230)
• Greatly improved OSX support (Martin Albrecht and Isuru Fernando https://github.com/fplll/fplll/issues/205,)
• Evaluator rewrite/refactoring now supporting different evaluation strategies (Marc Stevens https://github.com/fplll/fplll/pull/224)
• We now enforce coding conventions (Tancrède Lepoint https://github.com/fplll/fplll/pull/215, https://github.com/fplll/fplll/pull/219)

We also fixed various other issues, see https://github.com/fplll/fplll/compare/5.0.3…5.1.0 for details.
