Modeling is sometimes more an art than science. With experience you will become pragmatic and be able to find the right tradeoff ...

We now change the subject to talk about optimization in CP. You certainly know the Branch and Bound but do you know how this ...

In the project you will model the stable-matching. It remains one mystery that we still need to explain to you in this model. This is ...

The steel mill slab problem has an elegant model using element constraints and bin-packing formulation. You will play with this ...

It is time to introduce a new concrete optimization problem. Don't worry too much about optimization, we will cover that in Part 6, ...

So far, we have mainly discussed variable decisions. Let us now discuss the value decision in our automated search.

Filtering the 2D element constraint efficiently requires a lot of choices. What consistency do we want to achieve ? Then how to ...

For very small (functional) constraints such as X=Y+v, we do not really need to propagate them with the fix-point. Let us borrow the ...

As for the 2D Element filtering, we propose first a relaxed consistency not removing values in the middle of the domains of the ...

The previous filtering algorithm for table constraints is not the most efficient because it always restarts the computation from ...
