In this paper we present a new notion of what it means for a problem in P to be inherently sequential. Informally, a problem L is strictly sequential P-complete if when the best kn...
Various types of probabilistic proof systems have played a central role in the development of computer science in the last decade. In this exposition, we concentrate on three such...
Exotic semirings such as the “(max, +) semiring” (R ∪ {−∞}, max, +), or the “tropical semiring” (N ∪ {+∞}, min, +), have been invented and reinvented many times s...
Abstract. This paper deals with simulation and reversibility in the context of Cellular Automata (ca). We recall the de nitions of ca and of the Block (bca) and Partitioned (pca) s...
We consider the problem of maintaining a set of n integers in the range 0::2w ? 1 under the operations of insertion, deletion, predecessor queries, minimum queries and maximum quer...
