.... integrated constraint hierarchies with logic programming as hierarchical constraint logic programming (HCLP) and explored theoretical properties of HCLP [11, 90, 91, 92, 93] Jampel constructed a certain HCLP instance that separates the HCLP scheme into compositional and non compositional parts [50]. The method is expected to improve the efficiency of interpreters and compilers since the compositional part is efficiently implementable. Wolf formalized ordered constraint hierarchies by defining a hierarchy comparator that makes constraints totally ordered in each level, and also provided a ....

.... on theoretical properties did not cover local propagation on constraint hierarchies, but rather mainly focused on hierarchical constraint logic programming (HCLP) 11, 12, 13] Jampel constructed a certain HCLP instance that separates the HCLP scheme into compositional and non compositional parts [7]. The method is expected to improve the efficiency of interpreters and compilers since the compositional part is efficiently implementable. However, it is unclear whether such a method is applicable to local propagation. Freuder and Wallace proposed partial constraint satisfaction for handling ....
