Interprocedural Symbolic Range Propagation for Optimizing Compilers
Abstract. We have designed and implemented an interprocedural algorithm to analyze symbolic value ranges that can be assumed by variables at any given point in a program. Our algor...

Probabilistic algorithms for computing resultants
Let A and B be two polynomials in   [x,y] and let R = resx(A, B) denote the resultant of A and B taken wrt x. In this paper we modify Collins’ modular algorithm for computing R...

Exploiting the Tradeoff Between Precision and Cpu-Time to Speed Up Nearest Neighbor Search
We describe a recursive algorithm to quickly compute the N nearest neighbors according to a similarity measure in a metric space. The algorithm exploits an intrinsic property of a...

Fast k-Means Algorithms with Constant Approximation
In this paper we study the k-means clustering problem. It is well-known that the general version of this problem is NP-hard. Numerous approximation algorithms have been proposed fo...
