Towards an Efficient Tile Matrix Inversion of Symmetric Positive Definite Matrices on Multicore Architectures
The algorithms in the current sequential numerical linear algebra libraries (e.g. LAPACK) do not parallelize well on multicore architectures. A new family of algorithms, the tile a...

Cryptanalysis of 2R- Schemes
Abstract. In this paper, we study the security of 2Rschemes [17,18], which are the "minus variant" of two-round schemes. This variant consists in removing some of the n p...

Output-sensitive construction of the union of triangles
We present an efficient algorithm for the following problem: Given a collection T = {1, . . . , n} of n triangles in the plane, such that there exists a subset S T (unknown to us)...
