14th IEEE International Conference on Data Mining (IEEE ICDM)
作者: Avrachenkov, K. Litvak, N. Prokhorenkova, L. Ostroumova Suyargulova, E. Inria Rocquencourt France Univ Twente NL-7500 AE Enschede Netherlands Yandex Moscow Russia
In this paper we address the problem of quick detection of high-degree entities in large online social networks. Practical importance of this problem is attested by a large number of companies that continuously collec... 详细信息

17th Annual Conference on Theory and Applications of Models of Computation (TAMC)
作者: Sun, Yunjing Liu, Yuezhu Li, Min Shandong Normal Univ Sch Math & Stat Jinan 250014 Peoples R China
A k-submodular function is a promotion of a submodular function, whose domain is composed of k disjoint subsets rather than a single subset. In this paper, we give a deterministic algorithm for the non-monotone k-subm... 详细信息

50th Annual ACM SIGACT Symposium on the Theory of Computing (STOC)
作者: Fineman, Jeremy T. Georgetown Univ Washington DC 20057 USA
One of the simplest problems on directed graphs is that of identifying the set of vertices reachable from a designated source vertex. This problem can be solved easily sequentially by performing a graph search, but ef... 详细信息

54th Annual ACM SIGACT Symposium on Theory of Computing (STOC)
作者: Chi, Shucheng Duan, Ran Xie, Tianle Zhang, Tianyi Tsinghua Univ Beijing Peoples R China Tel Aviv Univ Tel Aviv Israel
In this paper, we show that the time complexity of monotone minplus product of two n x n matrices is (O) over tilde (n((3)(+omega)()/2)) = (O) over tilde (n(2.687)), where omega (n((3)(+omega)()/2)) time, which greatl... 详细信息

20th ACM SIGKDD International Conference on Knowledge Discovery and Data Mining (KDD)
作者: Yoshida, Yuichi Natl Inst Informat Tokyo Japan Preferred Infrastruct Inc Tokyo Japan
Betweenness centrality measures the importance of a vertex by quantifying the number of times it acts as a midpoint of the shortest paths between other vertices. This measure is widely used in network analysis. In man... 详细信息

20th International Symposium on Stabilization, Safety, and Security of Distributed Systems (SSS)
作者: Kunne, Stephan Cohen, Johanne Pilard, Laurence Univ Paris Saclay Univ Paris Sud LRI CNRS Orsay France Univ Paris Saclay LI PaRAD Univ Versailles St Quentin Versailles France
We analyse the impact of transient and Byzantine faults on the construction of a maximal matching in a general network. We consider the self-stabilizing algorithm called AnonyMatch presented by Cohen et al. [3] for co... 详细信息

33rd IEEE International Conference on Acoustics, Speech and Signal Processing
作者: Kar, Soummya Moura, Jose M. F. Carnegie Mellon Univ Dept Elect & Comp Engn Pittsburgh PA 15213 USA
The paper studies distributed average consensus in sensor networks, when the sensors exchange quantized data at each time step. We show that randomizing the exchanged sensor data by adding a controlled amount of dithe... 详细信息

40th IEEE International Conference on Distributed Computing Systems (ICDCS)
作者: Eguchi, Ryota Kitamura, Naoki Izumi, Taisuke Nagoya Inst Technol Dept Comp Sci Nagoya Aichi Japan
In the rendezvous problem, two computing entities (called agents) located at different vertices in a graph have to meet at the same vertex. In this paper, we consider the synchronous neighborhood rendezvous problem, w... 详细信息
