atmost(+N, ?List, +V)

At most N elements of the list List have the value V.
An integer
A list of domain variables or integers
An integer


If List is a list of domain variables and/or integers, this constraint takes care that at most N element of this list have the value V. As soon as some domain variable from the list is updated, this constraint is woken and it checks if the constraint is still satisfiable and if so, if it is already satisfied or not.

Fail Conditions

Fails if more than N elements of List are instantiated to V.
