JSR-331 Downloads

To start working with JSR-331 you only need its Technology Compatibility Kit (TCK) that include executables and examples for common software and for all included implementations. You also may download the specification Javadoc with its public interfaces, source code, implementations with linear solvers, and additional features not yet included ion the standard.

Main JSR-331 Downloads:

• Technology Compatibility Kit (with all executables)
  • The Eclipse project "org.jcp.jsr331.tck" with working examples and all supporting libraries
  • Unzip and import the project "org.jcp.jsr331.tck" "to your Eclipse workspace
  • This project is sufficient to use JSR-331 to develop custom CP-based engines using included JSR-331 implementations
  • Read "jsr331.readme.txt"
  • Licenses
    • The Specification license is in the file "jsr331.license.txt"
    • Licenses for particular solvers included into the TCK are located together with jar-files in the proper sub-folders of the folder "lib".
• JSR-331 Javadoc

Additional JSR-331 Downloads:

• Linear Solver Implementation Kit (Beta)
  • The Eclipse project "org.jcp.jsr331.tck" includes the package "org.jcp.jsr331.linear.samples" with working examples of linear optimization problems
  • All jar-files for LP  implementations are located inside the folder "lib/linear/".
  • Make sure that you downloaded and insta lled the proper LP solver from its original website and check that it works from a command line
  • Set up the properties of the project "org.jcp.jsr331.linear.samples" making sure that it include a common jar "org.jcp.jsr331.linear.jar" and solver-specific jar, e.g. "org.jcp.jsr331.scip.jar"
    
• Source Code
  • Specification with common implementation
    • Unzip and import the project "org.jcp.jsr331" to your Eclipse workspace

    • Temporarily withdrawn
  • JSetL implementation
    • Unzip and import the project "org.jcp.jsr331.setl" to your Eclipse workspace
  • Linear Solvers
    • Unzip and import the project "org.jcp.jsr331.linear" with solver-independent LP implementation to your Eclipse workspace
    • Unzip all or some of the following projects with LP solver-specific implementations
      • CPLEX
      • GUROBI
      • COIN
      • GLPK
      • SCIP
      • LP_SOLVE
      • OJALGO
• Extra

  • This project contains additional examples that use features not yet included in the current release of the JSR-331. In particular, they cover reversible variables and reversible actions described by the interface "javax.constraints.extra".
