  Search algorithm:

  MTD(f) search. Multicore support: Internally, it uses work-stealing provided by the Threading Building Blocks library. Currently, there is still a known scalability bug in my implementation, so the speedup is not optimal.. Singular Extensions (SE): This is the most important algorithmical addition in comparison with Ghost 2. It was a clear improvement to the search. All in all, the search is fairly minimal. It is still work in progress and hopefully we will see some improvements in the near future. Cross-platform software – runs under Linux and Windows.
