To clearly understand what you are doing, you can write your expression in a different way: all_different ( [sequence [t,c] c in customers where sequence [c,t] != 0]) Note that this uses array comprehensions. These are great to express a lot of things, but if sequence is an array of variables then the number of ...

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].

I am solving a magical square (3x3) by Excel Solver to get sum of 15. This is working perfectly. But when I change the constraints to get total of 30 or 45, it is not solving. Why? It should solve. Technically the numbers of the matrix of 3x3 should just be multiplied by 2 and 3 to get 30 and 45 respectively. lyrics to early one morning
