Compact Routing in Power-Law Graphs
Abstract. We adapt the compact routing scheme by Thorup and Zwick to optimize it for power-law graphs. We analyze our adapted routing scheme based on the theory of unweighted rando...

A Fast General Methodology for Information - Theoretically Optimal Encodings of Graphs
We propose a fast methodology for encoding graphs with information-theoretically minimum numbers of bits. Specifically, a graph with property π is called a π-graph. If π satis...

Towards optimal bag-of-features for object categorization and semantic video retrieval
Bag-of-features (BoF) deriving from local keypoints has recently appeared promising for object and scene classification. Whether BoF can naturally survive the challenges such as ...

An O(nlogn) time algorithm for optimal buffer insertion
The classic algorithm for optimal buffer insertion due to van Ginneken has time and space complexity O(n2 ), where n is the number of possible buffer positions. We present a new a...
