On the Complexity of Unary Tiling-Recognizable Picture Languages
Abstract. We give a characterization, in terms of computational complexity, of the family Rec1 of the unary picture languages that are tiling recognizable. We introduce quasi-unary...

Interactive visibility culling in complex environments using occlusion-switches
: We present occlusion-switches for interactive visibility culling in complex 3D environments. An occlusionswitch consists of two GPUs (graphics processing units) and each GPU is u...

Optimal Query Complexity for Reconstructing Hypergraphs
In this paper we consider the problem of reconstructing a hidden weighted hypergraph of constant rank using additive queries. We prove the following: Let G be a weighted hidden h...

Complexity and Approximation Results for the Connected Vertex Cover Problem
We study a variation of the vertex cover problem where it is required that the graph induced by the vertex cover is connected. We prove that this problem is polynomial in chordal g...

The Complexity of Maximum Matroid-Greedoid Intersection
Abstract. The maximum intersection problem for a matroid and a greedoid, given by polynomial-time oracles, is shown NP-hard by expressing the satisfiability of boolean formulas in...
