In this study, we establish an interesting connection between two mathematical approaches to vagueness: rough sets and soft sets. Soft set theory is utilized, for the first time, to generalize Pawlak's rough set model. Based on the novel granulation ...
Constraints allow the declarative specification of various problems in many fields. In particular, constraint hierarchies that enable soft constraints with hierarchical preferences are useful for programming interactive graphical applications. However, ...
The semiring-based constraint satisfaction problems (semiring CSPs), proposed by Bistarelli, Montanari and Rossi [S. Bistarelli, U. Montanari, F. Rossi, Semiring-based constraints solving and optimization, Journal of the ACM 44 (2) (1997) 201-236], is a ...
