However, the constraint store may also contain constraints in the form t1!=t2, if the difference!
the other term can replace the variable in the current goal and constraint store, thus practically removing the variable from consideration.
On the other hand, in the second formulation the search is performed only when the constraint is already in the constraint store.
the first constraint is removed from the constraint store.
finite domains are allowed, the constraint store may also contain domain-specific constraints like X+2=Y/2, etc.
new constraint to the constraint store.
When rewriting a literal in the goal, the only considered clauses are those whose guard is entailed by the union of the constraint store and the equation of the literal with the clause head.
This addition makes the constraint store unsatisfiable, and the interpreter backtracks,
the interpreter first adds X>0 to the constraint store and then possibly evaluates B(X).
If the constraint store is unsatisfiable, this simplification may detect this unsatisfiability sometimes, but not always.
A first rule is that labeling literals should be placed after as much constraints on the labeled literals are accumulated in the constraint store.
A successful termination is generated when the current goal is empty and the constraint store is satisfiable.
After a constraint is added to the constraint store, some operations are performed on the constraint store.
The interpreter has proved the goal when the current goal is empty and the constraint store is not detected unsatisfiable.
Typically, constraint logic programs are written in such a way labeling literals are evaluated only after as many constraints as possible have been accumulated in the constraint store.
The second use of the labeling literal is to actually determine an evaluation of the variables that satisfies the constraint store.
partial satisfiability of the constraint store.
Logic programming clauses in conjunction with constraint handling rules can be used to specify a method for establishing the satisfiability of the constraint store.
its evaluation adds X<0 to the constraint store.
In particular, one may just save the changes to the constraint store made between two points of choice,
