A t-cover of a quadric Q is a set C of t-dimensional subspaces contained in Q such that every point of Q belongs to at least one element of C. We consider t-covers of the Klein quadric Q + (5, q). For t=2, we show that a 2-cover has at least q 2 +q elements, and we give an exact description of the e

In this paper we propose an efficient algorithm to implement parallel integer multiplication by a combination of parallel additions, shifts and reads from a memoryresident lookup table dedicated to squares.

We present an algorithm for solving the problem of globally minimizing a concave function over the integers contained in a compact polyhedron. The objective function of this problem need not be separable or even analytically defined. To our knowledge, the algorithm is the first ever proposed for thi
