New Release: toulbar2 v1.2.1

Pairwise consistency enforcing, XCSP3 format, multiCFN, and bicriteria optimization.

New Release: toulbar2 v1.2.0

Parallel Hybrid-Best First Search (compile from source, see README.md, and use mpirun -n [nbcores] toulbar2 problem.cfn). New documentation in Sphinx. Improved Python interface. Read XCSP3 format (still in progress). Improved knapsack constraint, used by default when searching for diverse solutions.

toulbar2 v1.1.1

Improved Python interface. See web/TUTORIALS/CFN.py. Add more tutorial examples. Simplify CMakeList.txt, compile on MacOS, and allows cross-compilation on Windows.

New release: 1.1.0

Toulbar2 1.1.0 includes a Python3 API (based on pybind), the ability to do incremental solving, to produce sequences of solutions with guaranteed diversity, pseudo-boolean constraints, a new reader for pseudo-boolean problems (.opb format) and new VAC-based variable ordering and upper-bounding heuristics.

New major release

Includes MPI-based parallel variable neighborhood search UDGVNS, a new CFN format (which allows for minimization and maximization, using decimal, possibly negative costs), and the clique cover global cost function.
