# atmost(+N, ?List, +V)

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

## Description

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.
### Resatisfiable

No.
