Double Dummy Solver

Deal now has a built-in double dummy solver, as provided by Bo Haglund.

The command for accessing the double dummy solver is documented here.

Deal currently contains the code for DDS 1.1.8.

While DDS is fairly fast most of the time, on some deals, it can take a long time. In particular, when there are lots of voids, can take several minutes to analyze the board.

For example, in this deal: 

          S: ---
          H: QT97
          D: AJ432
          C: K865
 S: K865           S: QT97
 H: ---            H: AJ432
 D: QT97           D: K865
 C: AJ432          C: ---
          S: AJ432
          H: K865
          D: ---
          C: QT97

DDS takes more than 20 minutes to analyze South declaring Notrump.
