Say that f : {0, 1}n → {0, 1} -approximates g : {0, 1}n → {0, 1} if the functions disagree on at most an fraction of points. This paper contains two results about approximatio...
We revisit the problem of memory checking considered by Blum et al. [3]. In this model, a checker monitors the behavior of a data structure residing in unreliable memory given an a...
Abstract. In this work we study the tractability of well supported approximate Nash Equilibria (SuppNE in short) in bimatrix games. In view of the apparent intractability of constr...
Given string T = T[1, . . . , n], the suffix sorting problem is to lexicographically sort the suffixes T[i, . . . , n] for all i. This problem is central to the construction of suf...
We study the classic problem of estimating the sum of n variables. The traditional uniform sampling approach requires a linear number of samples to provide any non-trivial guarante...
