# alldifferent_t(+Xs, +Cs, +MC)

Tentative value implementation of alldifferent/2 constraint
*Xs*
- A list or array of variables/values
*Cs*
- A list or array of numbers
*MC*
- A monitored_constraint descriptor

## Description

Tentative value implementation of alldifferent constraint with
offsets. The difference releationship must hold between the
values resulting from adding each variable Xi to its corresponding
offset Ci.
The violatedness of the constraint is the number of identical
value pairs among these Xi+Ci values.

The following declaration is in effect, meaning that alldifferent_t/3
is used whenever alldifferent/2 is added to a constraint set:

:- alldifferent_t/3 tent_implements alldiffernet/2.

### Modes and Determinism

- alldifferent_t(+, +, +) is det

## Examples

?- Xs = [A,B,C], Xs tent_set [1,2,3], CS :~ alldifferent(Xs, [1,0,0]).
Xs = [A{1 -> 1}, B{2 -> 1}, C{3 -> 0}]
CS = constraint_set(TotalVio{1 -> 0}, ...)
There is 1 delayed goal.
Yes (0.00s cpu)
