Diffusive capture processes for information search
Sungmin Lee, Soon-Hyung Yook, Yup Kim
We show how effectively the diffusive capture processes (DCP) on complex networks can be applied to information search in the networks. Numerical simulations show that our method g…
Statistical properties of sampled networks by random walks
Sooyeon Yoon, Sungmin Lee, Soon-Hyung Yook +1
We study the statistical properties of the sampled networks by a random walker. We compare topological properties of the sampled networks such as degree distribution, degree-degree…
Dynamical Structures of High-Frequency Financial Data
Kyungsik Kim, Seong-Min Yoon, Soo Yong Kim +2
We study the dynamical behavior of high-frequency data from the Korean Stock Price Index (KOSPI) using the movement of returns in Korean financial markets. The dynamical behavior f…
