When we initiated JSR-331 standard, the choice of Java was justified (besides other practical advantages) by the fact that users would be able to create their own friendly DSLs (domain specific languages) using different JVM languages.  Probably it will be … Continue reading →

Oscar Riveros used JSR-331 to develop a Clojure-based environment for solving puzzles. You may read more in this manual “Constraint Programming with Puzzles“. All sources and examples are freely available from GitHub. I haven’t had a chance to check it myself … Continue reading →

This year the major annual conference “CP 2013“ will include a workshop “CP Solvers: Modeling, Applications, Integration, and Standardization” that will be held in Uppsala, Sweden on September 16, 2013.

I plan to present the latest state of the JSR-331 standard at the major CP conference CPAIOR that will be held at Yourtown Heights, NY, USA on May 18-22, 2013.

I am presenting Constraint Programming for Java Developers at the JavaOne conference on Oct.1 at 10:00 – 11:00 am in San Francisco

Narendra Jussien has presented JSR-331 at The 21st International Symposium on Mathematical Programming ISMP-2012.  

As we planned from the very beginning, now we’ve successfully added 6 more JSR-331 implementations using various open source and commercial Linear Programming (LP) tools. 

JSR-331 successfully passed the Final Approval Ballot. The JCP Executive Committee that includes representatives of IBM, RedHat, Fujitsu, Intel, SAP, Eclipse, HP, and others voted “Yes” on the Final Release that we submitted in January.

Everybody who is interested in using constraint programming tools in Java may now download JSR-331 v. 1.0.0 from http://openrules.com/jsr331.   You may download JSR-331 executables and sources, try multiple examples of constraint satisfaction and optimization problems, and start writing CP-based engines for your … Continue reading →
