In this paper we propose a new integer programming formulation for the multilevel facility location problem and a novel 3-approximation algorithm based on LP rounding. The linear ...
A fast and new heuristic recursive algorithm to find a minimum height for two-dimensional strip rectangular packing problem is presented. This algorithm is mainly based on heurist...
Several variants of new digital signature schemes (DSS) based on the discrete logarithm and factorization problems have been proposed. Considered DSS are characterized in that a n...

We present a new short signature scheme based on a variant of the Boneh-Boyen's short signatures schemes. Our short signature scheme is secure without requiring the random or...
In 2006, Smith et al. published a new table of constant weight codes, updating existing tables originally created by Brouwer et al. This paper improves upon these results by fill...
