Hi, I have added ¯4 ⎕DLX B. It simplifies the presetting of values for a given constraints matrix B. This can be useful, for example, for Sudokus to place the given digits into the contraints matrix of an empty Sudoku. The solving of Sudokus is now down to around 5 lines of APL code (not counting comments, formatting etc). See: http://www.gnu.org/software/apl/Bits_and_Pieces/sudoku_DLX.html /// Jürgen |
