  • Support for solver-independent JSR-331 implementations using Linear Solvers. This release includes:
  • TCK includes two new packages:
    • "" - a set of linear problems that can be solved using both CP and LP implementations
    • "" - a collection of test problems contributed by Hakan Kjellerstrand
  • More advanced search for optimal solutions:
    • Introduced 3 optimization strategies: BASIC, DICHTOMIZE, and NATIVE (solver-specific)
    • An ability to limit time for search of one solution and for the entire optimization process
  • The use of dynamic list of constrained integer variables
