2018-10-09Refactoring of Micromega code using a Simplex linear solverFrédéric Besson
- Simplex based linear prover Unset Simplex to get Fourier elimination For lia and nia, do not enumerate but generate cutting planes. - Better non-linear support Factorisation of the non-linear pre-processing Careful handling of equation x=e, x is only eliminated if x is used linearly - More opaque interfaces (Linear solvers Simplex and Mfourier are independent) - Set Dump Arith "file" so that lia,nia calls generate Coq goals in filexxx.v. Used to collect benchmarks and regressions. - Rationalise the test-suite example.v only tests psatz Z example_nia.v only tests lia, nia In both files, the tests are in essence the same. In particular, if a test is solved by psatz but not by nia, we finish the goal by an explicit Abort. There are additional tests in example_nia.v which require specific integer reasoning out of scope of psatz.
2018-06-07Micromega clean-upMaxime Dénès
We add .mli files, removed dead code and use standard combinators instead of redefined ad-hoc ones in a few places. A lot of cleaning still has to be done on this code: documenting the interfaces, resolving the many abstraction leaks. I suspect there is still a lot of code duplication.

2012-11-08Monomorphized a lot of equalities over OCaml integers, thanks toppedrot
the new Int module. Only the most obvious were removed, so there are a lot more in the wild. This may sound heavyweight, but it has two advantages: 1. Monomorphization is explicit, hence we do not miss particular optimizations of equality when doing it carelessly with the generic equality. 2. When we have removed all the generic equalities on integers, we will be able to write something like "let (=) = ()" to retrieve all its other uses (mostly faulty) spread throughout the code, statically. git-svn-id: svn+ssh://scm.gforge.inria.fr/svn/coq/trunk@15957 85f007b7-540e-0410-9357-904b9bb8a0f7
