Relating Tree Series Transducers and Weighted Tree Automata
Bottom-up tree series transducers (tst) over the semiring A are implemented with the help of bottom-up weighted tree automata (wta) over an extension of A. Therefore bottom-up D-w...

Approximation algorithms for stochastic orienteering
In the Stochastic Orienteering problem, we are given a metric, where each node also has a job located there with some deterministic reward and a random size. (Think of the jobs as...

Materializing views with minimal size to answer queries
In this paper we study the following problem. Given a database and a set of queries, we want to find, in advance, a set of views that can compute the answers to the queries, such ...
