Computing the Transitive Closure of a Union of Affine Integer Tuple Relations
Abstract. This paper proposes a method to compute the transitive closure of a union of affine relations on integer tuples. Within Presburger arithmetics, complete algorithms to com...

Intersecting quadrics: an efficient and exact implementation
We present the first complete, exact, and efficient C++ implementation for parameterizing the intersection of two implicit quadrics with integer coefficients of arbitrary size. It...

Tolerance Based Contract-or-Patch Heuristic for the Asymmetric TSP
In this paper we improve the quality of a recently suggested class of construction heuristics for the Asymmetric Traveling Salesman Problem (ATSP), namely the Contract-or-Patch heu...

On Minimal Perimeter Polyminoes
This paper explores proofs of the isoperimetric inequality for 4-connected shapes on the integer grid Z2 , and its geometric meaning. Pictorially, we discuss ways to place a maxima...

Skeletonization and Distance Transforms of 3D Volumes Using Graphics Hardware
We propose a fast method for computing distance transforms and skeletons of 3D objects using programmable Graphics Processing Units (GPUs). We use an efficient method, called dista...
