Approximation Schemes for Steiner Forest on Planar Graphs and Graphs of Bounded Treewidth
We give the first polynomial-time approximation scheme (PTAS) for the Steiner forest problem on planar graphs and, more generally, on graphs of bounded genus. As a first step, w...

An Optimal Randomised Cell Probe Lower Bound for Approximate Nearest Neighbour Searching
We consider the approximate nearest neighbour search problem on the Hamming cube {0, 1}d. We show that a randomised cell probe algorithm that uses polynomial storage and word size...

Logics and Models of Real Time: A Survey
We survey logic-based and automata-based languages and techniques for the speci cation and veri cation of real-time systems. In particular, we discuss three syntactic extensions of...

Response time analysis of software transactional memory-based distributed real-time systems
We consider distributed real-time systems where concurrency control is managed using software transactional memory. For such a method we propose an algorithm to compute an upper b...

RACBVHs: random-accessible compressed bounding volume hierarchies
We present a novel bounding volume hierarchy (BVH) compression and decompression method transparently supporting random access on the compressed BVHs. To support random access on ...
