Overlapping Alldifferent Constraints and the Sudoku puzzle (2009)
F. Lardeux, E. Monfroy, F. Saubion, B. Crawford, C. Castro
Abstract. Combinatorial problems can be modeled as constraint satisfaction problems (CSP). Modeling and resolution of CSP is often strengthened by global constraints (e.g., Alldiff constraint). We...
