Selection Functions that Do Not Preserve Normality
The sequence selected from a sequence R(0)R(1) . . . by a language L is the subsequence of R that contains exactly the bits R(n + 1) such that the prefix R(0) . . . R(n) is in L. B...

Complexity of the Exact Domatic Number Problem and of the Exact Conveyor Flow Shop Problem
We prove that the exact versions of the domatic number problem are complete for the levels of the boolean hierarchy over NP. The domatic number problem, which arises in the area of...

Simple Efficient Load-Balancing Algorithms for Peer-to-Peer Systems
Load balancing is a critical issue for the efficient operation of peerto-peer networks. We give two new load-balancing protocols whose provable performance guarantees are within a...

Reachability Problems on Regular Ground Tree Rewriting Graphs
We consider the transition graphs of regular ground tree (or term) rewriting systems. The vertex set of such a graph is a (possibly infinite) set of trees. Thus, with a finite tree...
