Parent-Version:      1.7
Version-Log:

Implement a new drawing policy in polyhedron.

The idea is to base the base (which is not so expensive), and to draw
in othogonal hypercube that is as small as possible until a point in
the polyhedron is found.  However, it may happens in high dimension (>4)
that the volume of the cube is much bigger. In that case, after a few tries,
i call the old (unfair) method.

polyDram.ml/mli:
   new module containing all the thing related to the drawing inside
   a convex polyhedron.

   Give up the idea of random walk (not clear what should be the default
   step and length in big dimension).

source/fair_bddd.ml: [new]
source/fair_bddd.mli: [new]
   The same as bddd, but taking polyhedron volume into account.

source/bddd.ml:
   It is useless to store both bdd and not bdd, because it is just
   so easy to recompute the sol nb of not bdd (by switchinf the
   pair of sol numbers!).

source/lurettetop.ml:

Project-Description: Lurette

Parent-Version:      0.121
Version-Log:

When delayed constraints are remaining at bdd leaves, we were
printing a message saying that one shoud use a polyhedron solver
based instead.  Now, I really call such a polyhedron solver in order
to solve those constraints.

This means that I use to different solvers to handle interval and
polyhedron of dimension > 1.

It also means that the satisfiability of constraints over polyhedra
is only checked at bdd leaves, which, in some circumstances, migth be
inefficient. The point is that, if we chose to check the formula
satisfiability during the bdd traversal, we take the risk that a very
polyhedron is created whereas it was not necessary (because of
forthcoming equalities). And creating polyhedron with big (>15)
dimension simply runs forever, which is really bad.

nb : drawing in poyhedron not yet plugged.

source/polyhedron.ml:
source/polyhedron.mli: (new files)
    misc functions over polyhedra. The rational for creating that file
    is that rnumsolver is already much too big (and should be splitted
    some more btw).

source/solver.ml:
   One of the main change is that now, draw_in_bdd returns 2 stores.
   One is Range based, the other one is polyhedron-based.

source/rnumsolver.mli:
source/rnumsolver.ml:
   Add the function switch_to_polyhedron_representation which
   handle delayed constraint if necessary. It is meant to be called
   at bdd leaves.

source/solver.ml:
source/rnumsolver.ml:
   Also do not use split_store anymore but add_constraint. This allows
   a much more elegant and efficient implementation of draw_in_bdd and
   draw_in_bdd_eq (Now the store is buid when and only when a new branch
   should be tried because of backtracking). It is also more efficient.

source/rnumsolver.ml:
   Reimplement split_store so that it uses 2 calls of add_constraint
   instead of doing the work twice inside split_store (in order to avoid code
   duplication).

   Also, whenever delayed constraints becomes of dimension 1, when a
add_constraint
   binds a value, add them to the store.

   Enhance error msgs whenever int and float are mixed in the same lucky
   expressions.

source/rnumsolver.ml:
source/ne.ml:
   rename Ne.resolve_triangular_system into get_subst_from_solved_system
