# Granular Computing – The Concept of Generalized Constraint-Based Computation

## Abstract

Basically, granular computing is a mode of computing in which the objects of computation are granular variables. Let *X* be a variable which takes values in a universe of discourse, *U*. Informally, a granule is a clump of elements of *U* which are drawn together by indistinguishability, similarity or proximity. For example, an interval is a granule; so is a fuzzy interval; so is a gaussian distribution; and so is a cluster of elements of *U*. A granular variable is a variable which takes granules as values. If *G* is value of *X*, then *G* is referred to as a granular value of *X*. If *G* is a singleton, then *G* is a singular value of *X*. A linguistic variable is a granular variable whose values are labeled with words drawn from a natural language. For example, if *X* is temperature, then 101.3 is a singular value of temperature, while “high” is a granular (linguistic) value of temperature.
