Dear users,

JaCoP 4.2 has been released. Feel free to download a compiled version from http://sourceforge.net/projects/jacop-solver/ or to clone JaCoP repository from https://github.com/radsz/jacop  and contribute.

This release contains several new features and improvements. First, this version is compatible with newly released minizinc 2.0. Please, use the new JaCoP minizinc library from directory src/main/minizinc/org/jacop/minizinc/ when compiling minizinc files. It offers newly introduced, in minizinc, global constraints knapsack, network_flow and geost. We have also developed a flatzinc loader that makes it possible to load flatzinc models and then use the created model in Java. 

The new search method, SGMPCS search, has been added to the solver . It is based on the original work by J. C. Beck and presented in the paper entitled "Solution-Guided Multi-Point Constructive Search for Job Shop Scheduling". 

Directory org.jacop.examples.flatzinc contains examples of applications for flatzinc loader, SGMPCS search and minimization method for floating point problems.

This release fixes also few bugs and makes improvements in several parts of the solver.

Best regards,
JaCoP Core Developer Team
