The Sketching Complexity of Pattern Matching
Abstract. We address the problems of pattern matching and approximate pattern matching in the sketching model. We show that it is impossible to compress the text into a small sketc...

Optimal Rewritings in Definitorially Complete Description Logics
In this paper, we revisit the problem of definitorial completeness, i.e., whether a given general TBox T in a description logic (DL) L can be rewritten to an acyclic TBox T in L . ...

An Experimental Study of Random Knapsack Problems
The size of the Pareto curve for the bicriteria version of the knapsack problem is polynomial on average. This has been shown for various random input distributions. We experimenta...

New Bounds on the Capacity of Multi-dimensional RLL-Constrained Systems
Abstract. We examine the well-known problem of determining the capacity of multi-dimensional run-length-limited constrained systems. By recasting the problem, which is essentially ...
