Your expression of this global constraint as a series of binary inequalities is a valid approach however the issue you are encountering is a reflection of the difficulty of determining whether two floats are different (which is a broader issue … Weballdifferent constraint [Lauriere, 1978] is a type of global constraint where all variables must have different values. The alldifferent constraint is one of the most important and diffi-cult types of constraints and appears in many applications, such as puzzles, graph coloring, scheduling, and recommen-dation or matchmaking [Hoeve, 2001].

WebYou can define linear constraints as in: model.Add (x + 2 * y <= 5) model.Add (sum (array_of_vars) == 5) In CP-SAT, the objective is a linear expression: model.Minimize (x + 2 * y + z) For large arrays, using the LinearExpr class is faster that using the python sum () function. You can create constraints and the objective from lists of linear ... WebA constraint such as A1:A5 = alldifferent, where A1:A5 are decision variable cells, requires that these cells must be integers in the range 1 to N (N = 5 in this example), with each …
