jConstraints-dReal

This adds support for the dReal constraint solver in jConstraints. Please consult the dReal website for more information.

NOTE This plugin is at the moment very experimental with some features being incomplete.

Installation

First, get dReal from dReal website. Then:

• Go to the jConstraints-dreal folder and run mvn install. It should run a lot of test cases - hopefully everything works.
• If the compilation was successful, the jConstraints-dreal library can be found in the JAR file target/jConstraints-dreal[VERSION].jar
• jConstraints loads extensions automatically from the ~/.jconstraints/extensions folder in a users home directory. Create this directory and copy jConstraints-dreal-[version].jar into this folder.

Usage and Configuration

To use dreal, simply put the following in your .jpf file.

symbolic.dp=dreal
dreal.path=/path/to/dReal/executable

More options will be added soon.

Cannot handle (Coral can):

(set-logic QF_NRA)
(declare-fun y () Real)
(declare-fun x () Real)
(assert (= y ( cos x)) )
(check-sat)
(exit)

or

(set-logic QF_NRA)
(declare-fun x1 () Real)
(declare-fun x2 () Real)
(assert (= (- ( sin x1) ( cos x2)) 0.0) )
(check-sat)
