Sat4j


Sat4j is a library aiming at providing a simple and efficient open source library of SAT solvers in Java.

The aim of the Sat4j library is to provide a simple and efficient open source library of SAT solvers in Java. The Sat4j library targets first users of SAT "black boxes", willing to embed SAT technologies into their application without worrying about the details. Sat4j is currently the most widely deployed SAT framework because of its adoption within the Eclipse Open platform. Sat4j is available under both the Eclipse Public License and the GNU LGPL licence.

Market Readiness Synthesis


Sat4j is a popular, full featured, robust, user friendly, java solver used in software engineering, constraint programming, AI and software verification. Since Daniel Le Berre started developing Sat4j in 2004 at Lens University’s IT Research Center (CRIL), it has been downloaded more than 200,000 times from the OW2 forge. Moreover, as it is integrated in the Eclipse IDE, Sat4j is used by millions of people across the globe. Sat4j is a highly recognised and trustworthy tool, a true leader in its category even if, as a typical community project, there is no formal business activity around it hence its MRL score.
