Large Constraint Joins and Disjoint Decompositions


This paper is devoted to the problem of evaluation of a conjunction of N disjunctions of linear constraints in R (constraint join), which is a common constraint database operation. Existing methods are exponential in N . Here combinatorial geometry methods are applied to establish conditions for a polynomial size of the join output. A polynomial method to… (More)
