Detailed Description

Example: Crossword puzzle

Fill crossword grids with words, that is construct a crossword puzzle. For a recent paper on this classical problem, see: Crossword Puzzles as a Constraint Problem, Anbulagan and Adi Botea, CP 2008, pages 550-554, Springer Verlag.

Note that "Modeling and Programming with Gecode" uses this example as a case study.
