One-way communication complexity of symmetric boolean functions

Jan Arpe, Andreas Jakoby, Maciej Liśkiewicz (2005)

RAIRO - Theoretical Informatics and Applications - Informatique Théorique et Applications

Similarity:

We study deterministic one-way communication complexity of functions with Hankel communication matrices. Some structural properties of such matrices are established and applied to the one-way two-party communication complexity of symmetric Boolean functions. It is shown that the number of required communication bits does not depend on the communication direction, provided that neither direction needs maximum complexity. Moreover, in order to obtain an optimal protocol, it is in any case...

The Communication Hierarchy of Time and Space Bounded Parallel Machines

Norbert Popély (2010)

RAIRO - Theoretical Informatics and Applications

Similarity:

We describe the communicating alternating machines and their simulation. We show that, in the case of communicating alternating machines which are bounded, simultaneously, by polynomial time and logarithmic space, the use of three communication levels instead of two does not increase computational power of communicating alternating machines. This resolves an open problem [2] concerning the exact position of machines with three communication levels in the hierarchy.

Designing an E-Mail Prototype to Enhance Effective Communication and Task Management: A Case Study

Katz, Adi, Berman, Irit (2011)

Serdica Journal of Computing

Similarity:

This paper deals with communicational breakdowns and misunderstandings in computer mediated communication (CMC) and ways to recover from them or to prevent them. The paper describes a case study of CMC conducted in a company named Artigiani. We observed communication and conducted content analysis of e-mail messages, focusing on message exchanges between customer service representatives (CSRs) and their contacts. In addition to task management difficulties, we identified communication...
