added translation for Const

part 1 and 3 of translation

a91110f4 05/03/2017 03:47 PM Kristin Braun

first part of translations is implemented

3cd07e5d 05/03/2017 03:26 PM Hans-Peter Deifel

Replace String.split_on_char with custom implementation

String.split_on_char was introduced in OCaml 4.04, but we want to
support 4.02.

f24367c4 04/06/2017 05:57 PM Hans-Peter Deifel

Add command line flag for fragment

The user can now choose which fragment of the mu-calculus the reasoner
uses. More specialized fragments can have better performance
characteristics.

7ed16bab 04/06/2017 05:57 PM Hans-Peter Deifel

Add tests for command line option parser

4c23563e 04/06/2017 05:57 PM Hans-Peter Deifel

Generalize command line argument parsing

Adds a new module CoolUtils.Args that implements a generic command
line argument parser. This makes it easier to add new options to the
main program.

coalg: Make 'graph' subcommand more cli-friendly

- Read only one formula, we also only generate one graph
- Don't print a prompt or the satisfiability result

This allows to redirect the output graph to a file or directly to dot.

c4503f4f 04/06/2017 05:57 PM Hans-Peter Deifel

tests: Add dividing example for aconjunctive fragment

256444ba 04/06/2017 05:57 PM Hans-Peter Deifel

tests: Add unit tests

Adds a whole new set of tests that don't just test the whole reasoning
process on a formula, but smaller individual functions.

Right now there are only two tests but more should follow.

3d2f5068 04/06/2017 05:57 PM Hans-Peter Deifel

tests: Don't use exit status 0 if tests failed

93ef4736 04/06/2017 05:57 PM Hans-Peter Deifel

Fix aconjunctive fragment for rules with >1 children

Previously, the algorithm for the aconjunctive fragment would insert
many cores for each child of a modal rule and add those as children of
the rule application to the state.

This was wrong for multiple reasons:...

aa4d3606 04/06/2017 05:57 PM Hans-Peter Deifel

Add CoolUtils.TList.combinations function

4a20854e 04/06/2017 05:57 PM Hans-Peter Deifel

tests: Print summary for failed tests at the end

Makes it easier to find failing formulas for further fine-grained
analysis.

0d6818bb 04/06/2017 05:57 PM Hans-Peter Deifel

tests: Add example where new Algorithm should fail

This formula is not aconjunctive and should be wrongly declared as
satisfiable by the algorithm that assumes aconjunctivity.

This doesn't work right now: The new algorithm also answers with
"unsat".

b6653b96 04/06/2017 05:57 PM Hans-Peter Deifel

Don't hardcode check for aconjunctive formulas

Previously, cool would simply raise an exception if the formula was
not aconjunctive. This was done to ease testing of the new reasoner
algorithm.

Now, the reasoner decides whether the formula is aconjunctive or not...

bc706b79 04/06/2017 05:56 PM Hans-Peter Deifel

Add test cases for aconjunctive fragment

This fails currently, because the check for aconjunctivity is
currently hard coded, ruling out all formulas that aren't
aconjunctive.

e7aaefa9 04/06/2017 05:56 PM Hans-Peter Deifel

Specialize deferral tracking for aconjunctive fragment

For the aconjunctive fragment, we replace the generation of a single
core with all tracked deferrals by the generation of multiple cores,
each annotated with a single deferral from the above set.

fdda99d4 04/06/2017 05:56 PM Hans-Peter Deifel

Add vim modelines to more files

8c810657 03/27/2017 08:36 AM Hans-Peter Deifel

tests: Throw error if child doesn't return 0 or 1

0 and 1 are used for Sat and Unsat respectively. But if the child
throws an exception, another exit status is returned which the parent
now recognizes.

ad0b75b1 03/26/2017 09:29 AM Hans-Peter Deifel

tests: Run reasoner in new process for each formula

As it stands, cool leaks tons of memory with each `isSat` call. Until
this is fixed, the new `--slow` testsuite would need at least 16GB of
memory if all formulas are decided in one process. Thus, we now call...

b002efa8 03/26/2017 09:29 AM Hans-Peter Deifel

Add lots of test cases for CTL.

This imports some of the quickly decidable ctl comparision benchmark
formulas into the test suite.

The testsuite also gained a --slow parameter, that enables slower (but
still fairly fast) formulas.

Enable documentation generation in oasis

Documentation can be built with: ocaml setup.ml -doc

debugger: Stop and print result if reasoner finishes

The 'step' command takes an optional repeat count. Now it stops
stepping and prints the result if the reasoner finishes before
reaching the specified number of steps.

86c2c2ee 03/22/2017 04:54 PM Hans-Peter Deifel

Prettify graphviz output

- Use more readable colors and proper spacing
- Differentiate between cores and states by shape
- Add a legend
- Teach debugger to optionally write graph to file instead of stdout

5f1ec830 03/22/2017 04:54 PM Hans-Peter Deifel

Add UTF-8 "Micro Sign" as syntax for 'mu'

This is easier to type with a standard compose key as opposed as the
arguably more correct "Greek Small Letter Mu".

371cb823 03/22/2017 04:54 PM Hans-Peter Deifel

Perform sat propagation in debugger step

Otherwise, the debugger would report the reasoner result to be "Sat"
when it should really be "Unsat".

bbd5d2db 03/22/2017 04:54 PM Hans-Peter Deifel

Fix command line argument check in debugger

e928d370 03/22/2017 04:52 PM Hans-Peter Deifel

Improve 'verify' subcommand of main program

- Show a prompt before each input.
- Don't die if the verification of a formula fails. Show an error
instead and accept the next input.

5736aabb 03/22/2017 02:05 PM Hans-Peter Deifel

Replace Array.exists by Array.fold_left

Array.exists is only available since OCaml 4.03.0 and we need to
support version at least version 4.02.3.

c4aee922 03/22/2017 02:05 PM Hans-Peter Deifel

Remove GMLMIP

This drops the rule implementation for GML and PML, because they were
relying on GMLMIP which complicated the build process and didn't work
completely. See Issue 19.

GML and PML are still implemented as functors but currently disabled.
To re-instantiate them, an OCaml implementation is needed.

a57eb439 03/21/2017 09:12 PM Hans-Peter Deifel

Fix another compiler warning

This fixes the warning "the label idx is defined in both types state
and core." by renaming the label to idxS and idxC respectively.

9fdc9f4d 03/16/2017 07:08 PM Hans-Peter Deifel

Get testsuite running again

Fixes the syntax of all tests that use R and B as identifiers, which
are keywords now.

Also disables all tests involving nominals as they are currently all
throwing exceptions.

3c42e3f1 03/16/2017 07:08 PM Hans-Peter Deifel

Fix testsuite for K

R and B are now keywords and were used as identifiers. Now, r and
b (lowercase) is used instead in the testcases. For consistency, all
other identifiers were lowercased, too.

9352b45f 03/16/2017 07:08 PM Hans-Peter Deifel

Fix compilation of gmlmip with newest ocaml

The CAMLparam0() macro must be invoked at the beginning of a function
that has local variables.

Only remove solver after Unsat Propagation

9f1263ec 04/19/2016 10:30 AM Christoph Egger

Deallocate satsolver once core becomes `Open`

The satsolver is reatined and only updated with new clauses for every
state that is generated out of a core. Once the core becomes Open (as
opposed to expandable), the solver is no longer needed.

This patch makes the solver a `Solver option` and gets it deallocated...
