ADDED: CLP(ℤ), Constraint Logic Programming over Integers

Browse Source

library(clpz) implements declarative integer arithmetic.

The most important predicates for reasoning about integers are:

    (#=)/2    equality
    (#\=)/2   disequality
    (#<)/2    less than
    (#>)/2    greater than
    (#=<)/2   less than or equal to
    (#>=)/2   greater than or equal to

In addition, the library provides several global constraints, such as
all_distinct/1 and global_cardinality/2, and reification predicates
that reflect the truth values of constraints into integer variables.

Enumeration predicates such label/1 and labeling/2 can be used to
search for solutions over finite domains.

Almost all Prolog programs also reason about integers. Therefore, I
recommend to add this library to your .scryerrc configuration file so
that declarative integer arithmetic is available in all your programs.
