| Abstract:This is a special issue with special interest in computability and computational
complexity with extensions to information and network analysis. It consists of seven
invited submissions each of which is carefully reviewed.
The paper entitled: The future of computer science by John E. Hopcroft, Sucheta
Soundarajan, and Liaoruo Wang, surveys some important topics and paradigm shift
in computer science with the new focus on large-scale data and network analysis.
The paper entitled: Holographic reduction: A domain changed application and
its partial converse theorems by Mingji Xia arises the new problem of the converse of
Valiant's holographic reductions, and partially answers this question, which makes a
significant contribution to the theory of holographic computation.
The paper entitled: On strings with trivial Kolmogorov complexity by George
Barmpalias studies the degree theoretic complexity of sets of strings with low algorithmic complexity, building a few fundamental results in the area of algorithmic
randomness.
The paper entitled: Color-Coding and its applications: A survey by Jianxin
Wang, Qilong Feng, Jianer Chen, describes a comprehensive survey on this important
topic of parameterized computation.
The paper entitled: Rent-or-Buy network design problem and the Sample-Augment
algorithm: A survey by Peng Zhang, gives a survey on approximation algorithms of
the recently active topic of the rent or buy network design.
The paper entitled: Kalimulin pairs of ** w-enumeration degrees by Ivan N.
Soskov and Mariya I. Soskov studies the new phenomena of omega-enumeration degrees which is a natural extension of the classical enumeration degrees.
The paper entitled: A toolkit for generating sentences from context-free grammars by Zhiwu Xu, Lixiao Zheng, and Haiming Chen, presents a toolkit for parsing
context-free grammars and generating valid sentences.
I would like to thank all authors for their contribution to this excellent issue,
which reflects both our traditional research on computability and computational complexity and the extensions of the theory to information and networks.
I am grateful to Prof. Ruqian Lu for inviting me to organize this special issue,
and thank both Professor Ruqian Lu and the members of the Editorial Board of
the International Journal of Software and Informatics for cooperation throughout the
preparation of this special issue. |
