CS 840 Unit 1: Models, Lower Bounds and getting around Lower Bounds: Transcript

Searching Given a large set of distinct keys preprocess them so searches can be performed as quickly as possible 1 CS 840 Unit 1 Models Lower Bounds and getting around Lower bounds Searching. Our result is modular 1 We describe a carefullychosen dynamic version of set disjointness the multiphase problem and conjecture that it requires 84861 time per operation All our lower bounds follow by easy reduction 2 We reduce 3SUM to the multipha The heart of this technique is a complex ity measure for multivariate polynomials based on the linear span of their partial derivatives We use the technique to obtain new lower bounds for computing sym metric polynomials which hold over 64257elds of Indeed developing bounds on the per formance of procedures can give complementary insights By exhibiting fundamental limits of performance perhaps over restricted classes of estimators it is possible to guarantee that an a lgorithm we have developed 2 - .
