In the context of previous work on redundant modeling, permutation problems and matrix modeling, we introduce the notion of partial redundant modeling and categorical channeling constraints. To do so, we look at problems with categorical structure. Categorical channeling constraints also introduce the more general notion of channeling constraints over global constraints in redundant models. This paper provides only the motivation for partial redundant modeling and channeling categorical constraints. Future work will include implementation and testing as well as checking for scalability and flexibility of the proposed technique.
