Rough Approximation Operators in Covering Approximation Spaces

2006
In this paper, we focus on the study of covering based rough sets in covering approximation spaces. Firstly, two pairs of covering approximation operators are reviewed, their properties are investigated. Secondly, Based on the covering of the covering approximation space, two new coverings of the universe are induced, by which two new pairs of covering

Multifunctions as Approximation Operations in Generalized Approximation Spaces

1998
An approximation space can be defined as a quintuple A = (T, U, F, Φ, Γ), where F : T → U is a multifunction and Φ and Γ are unary operations on the power set of U.

Screening with an Approximate Type Space [PDF]

, 2010
We re-visit the single-agent mechanism design problem with quasi-linear preferences, but we assume that the principal knowingly operates on the basis of only an approximate type space rather than the (potentially complex) truth. We propose a two-step scheme, the profit-participation mechanism, whereby: (i) the principal .takes the model seriously and ...
