An active constraint means that this factor is causing the limitation on the objective function. If an active constraint was amount of flour, then by increasing the flour available you could improve your …

Powerful constraint: enforces that all intervals in the array do not overlap with each other! What’s the makespan of this solution?

While we can not achieve rf to be zero, we can look for points where the gradient is perpendicular to the constraint. This gives us an optimal point under the con nement.

This strategy chooses the value (the color, in the map example) which rules out the fewer choices for the neighbouring variables in the constraint graph. In other words: it is the choice which leaves maximum …

Constraints are an ubiquitous concept, which in its broader sense pertains to every day experience: they represent the conditions which restrict our freedom of decision. In fact, how much our choices are …

Constraint programming (CP) is a general framework for modeling and solving CSP’s: Offers the user many kinds of constraints, which makes modeling easy and natural
