The Different Than Majority Labeling (DTML) problem has a simple polynomial time algorithm, but is not known to be in NC. In this paper, we show that the DTML problem is extremely unlikely to have an NC1 algorithm.
期刊介绍:
Parallel Processing Letters (PPL) aims to rapidly disseminate results on a worldwide basis in the field of parallel processing in the form of short papers. It fills the need for an information vehicle which can convey recent achievements and further the exchange of scientific information in the field. This journal has a wide scope and topics covered included: - design and analysis of parallel and distributed algorithms - theory of parallel computation - parallel programming languages - parallel programming environments - parallel architectures and VLSI circuits
