Parent-Version:      0.55
Version-Log:

Change the env format sligthly again :
 - adds the arcs and node numbers.
 - allows lists to end by a ;
 - add xor's

Project-Description: Lurette

Parent-Version:      0.54
Version-Log:

Allow equalities between formula by translating [A = B] into
[Or(And(A,B), And(Not(A), Not(B)))].

Fix a bug where lurette had a bad behaviour whenever a toss
was performed on a domain which size was bigger than max_int
or max_float.

Fix a bug where lurette was not handling env with both boolean and
numerical as output vars.  Also add a few comments in solver.ml along
the way.
Adds a local bool as an output of heater in order to test the fix
above.

Parent-Version:      0.50
Version-Log:

Change the way pre are translated in the .env file. Now
instead of writting "_pre2toto", one writes "pre(2,toto)".

But internally, it is handled the same way as before (i.e., the first
thing I do when parsing the env file is to transform "pre(2,toto)"
into "_pre2toto" (it makes the hangling of pre vars much more
homogeneous with the way the other vars are handled.

Also fix a bug where it was not possible to have a pre on input
vars because the update_pre was failing to proceed quietly  whenever
one of its var was not computable because its pre does have a value.
Also give an appropriate error message whenever the user wrongly
use a pre on a var that can not be computed.

Parent-Version:      0.49
Version-Log:

Add the possibility to put pragmas in the .env files.

Project-Description: Lurette

Parent-Version:      0.48
Version-Log:

Clean up a little bit the ima format to make it sipler to parse
and to avoid reducing  the naming space as much as possible.

Project-Description: Lurette

Parent-Version:      0.47
Version-Log:

Add support for (boolean and numeric) if-then-else.

Remove the eval.ml module as the replacement of pre and input
vars is now done in Solver.formula_to_bdd.

Add a new module gne.ml that provides a garded normal expressions
data structure that is used to handle if-then-elses.

Also introduce a new field to env_state called bdd_tbl_global which
is used to cache the result of formula_to_bdd for bdds that do not
depend on pre nor input vars. The field bdd_tbl which cache the other
reults is now cleared at each step because it is useless to store results
that depends on pre and inputs.

Parent-Version:      0.43
Version-Log:

Add the possibility to specify the min lower and upper bounds
in the env automata for output and local vars.

Project-Description: Lurette

Parent-Version:      0.40
Version-Log:

Change sligthly the ima format to make it more consistent.

Project-Description: Lurette

Parent-Version:      0.39
Version-Log:

Change the naming convention of prevars. Now, _pretoto is noted
_pre1toto, and _pre_pre_pretoto is noted _pre3toto.

Also fix a bug in the default initialization of ranges : min_float
is the smallest positive float, not the smallet one !!

Project-Description: Lurette

Parent-Version:      0.37
Version-Log:

With this change, lurette is now able to handle numeric variables
over intervals !

Project-Description: Lurette

Parent-Version:      0.35
Version-Log:

Add support to handle numerical contraints. The numerical stuff is
untested, but the boolean part works as before.

source/rnumsolver.mli:
source/rnumsolver.ml:
    New files implementing a numeric solver based on intervals.

source/*.ml:
    Change the var_type type from a string to a sum type containing
    the lower and upper bounds of numeric domains.

    Do not maintain a var_name to index correspondance, but a formula to
    index one. This is to be able to handle numerical constraint in bdds.
    This field is not set at init time anymore, but in formula_to_bdd.

    Add <>, <, and <= to the type of formula.

 Handle pre in formula and expressions. Also add (in
green) the environment local vars in the sim2chro output.

Now lurette can hanble multiple environements that can either be
run as a product or in parallel.
