Working with Multiple Data Sourcesmmar and the integer k are problem parameters) is shown to be complete for polynomial space (PSPACE) when k is expressed in unary, and complete for nondeterministic (one-level) exponential time (NE) when k is expressed in binary. This solves an open problem by Hunt, Szymanski and Ullman, who showed

Working with Multiple Data Sourcesot always polynomially bounded in the size of the grammar. A similar non-polynomial size difference occurs also in LL(k) parsers. We show that such non-polynomial size differences cannot be regarded as a weakness of the LR(k) or LL(k) parser construction methods but are a consequence of the capabili

While this paper‘s contribution is mainly theoretical, it points toward very practical directions: we show how to design multipliers with area A = O(N) and time T=O(√N(yùn)) on one hand, a

Minimum s-t cut of a planar undirected network in o(n log2(n)) time,ost) from a set L. This paper presents an algorithm for computing a minimum (cost) s-t cut of N. For general L, this algorithm runs in time O(n log.(n)) time on a (uniform cost criteria) RAM. For the case L contains only integers ≤n., the algorithm runs in time O(n log(n)loglog(n)). Our algorithm al
