In this paper, we proposed a new interval-valued approximation of interval-valued fuzzy numbers, which is the best one with respect to a certain measure of distance between interval-valued fuzzy numbers. Also, a set of criteria for interval-valued approximation operators is suggested.
We give a polynomial time approximation scheme (PTAS) for dense instances of the Nearest Codeword problem.

In this paper we give approximation algorithms for several proximity problems in high dimensional spaces. In particular, we give the rst Las Vegas data structure for (1 +)-nearest neighbor with polynomial space and query time polynomial in dimension d and logn, where n is the database size. We also give a deterministic 3-approximation algorithm with similar bounds; this is the rst deterministic...
Nearest neighbor (NN) queries in trajectory databases have received significant attention in the past, due to their application in spatiotemporal data analysis. Recent work has considered the realistic case where the trajectories are uncertain; however, only simple uncertainty models have been proposed, which do not allow for accurate probabilistic search. In this paper, we fill this gap by add...
