An Isomorphism between Subexponential and Parameterized Complexity Theory
We establish a close connection between (sub)exponential time complexity and parameterized complexity by proving that the so-called miniaturization mapping is a reduction preservi...

On Some Optimization Heuristics for Lesk-Like WSD Algorithms
For most English words, dictionaries give various senses: e.g., “bank” can stand for a financial institution, shore, set, etc. Automatic selection of the sense intended in a gi...

A Two-Pronged Attack on the Dragon of Intractability
One approach to tractably finding a solution to an NP-complete optimisation problem is heuristic, where the solution is inexact but quickly found; another approach is to reduce t...

On data structures and asymmetric communication complexity
c communication case. This lemma generalizes and abstracts in a very clean form the ``round reduction'' techniques used in many previous lower bound proofs. ] 1998 Academ...

Separating NE from Some Nonuniform Nondeterministic Complexity Classes
We investigate the question whether NE can be separated from the reduction closures of tally sets, sparse sets and NP. We show that (1) NE RNP no(1)-T (TALLY); (2)NE RSN m (SPARS...
