We provide a general formulation for the code-based test compression problem with fixed-length input blocks and propose a solution approach based on Evolutionary Algorithms. In c...
Computing multidimensional aggregates in high dimensions is a performance bottleneck for many OLAP applications. Obtaining the exact answer to an aggregation query can be prohibit...
The performance of question answering system is evaluated through successive evaluations campaigns. A set of questions are given to the participating systems which are to find the...

Abstract. In this paper we propose an optimal anytime version of constrained simulated annealing (CSA) for solving constrained nonlinear programming problems (NLPs). One of the goa...
Well-designed indices can dramatically improve query performance. Including query workload information can produce indices that yield better overall throughput while balancing the...
