Computation of reducts of composed information systems. (English)
[J] Ann. Soc. Math. Pol., Ser. IV, Fundam. Inf. 27, No.2-3, 183-195 (1996). ISSN 0169-2968

Summary: A set-theoretical approach to finding reducts of composed information systems is presented. It is shown how the search space can be represented in form of a pair of boundaries. It is also shown, how reducts of composing information systems can be used to reduce the search space of the composed system. Presented solutions are implied directly from the properties of composed monotonic Boolean functions.
