Agents Defined by Specific Codes

Constraint programming systems implement their built-in agents using specific codes which wake up, for example, whenever the upper or lower bound of the domain constraint on a given variable is altered.

Using specific codes it is also possible to build complex constraints and constraint behaviours to obtain good performance on large complex problems. Indeed this is the approach that has been very successfully applied on job-shop scheduling benchmarks and incorporated into commercial constraint programming tools such as CHIP and ILOG SCHEDULE.
