ProbeWalk: Fast Estimation of Biharmonic Distance on Graphs via Probe-Driven Random Walks
Dehong Zheng, Zhongzhi Zhang
The biharmonic distance is a fundamental metric on graphs that measures the dissimilarity between two nodes, capturing both local and global structures. It has found applications a…
Opinion Maximization in Social Networks by Modifying Internal Opinions
Gengyu Wang, Runze Zhang, Zhongzhi Zhang
Public opinion governance in social networks is critical for public health campaigns, political elections, and commercial marketing. In this paper, we addresse the problem of maxim…
Efficient Algorithms for Minimizing the Kirchhoff Index via Adding Edges
Xiaotian Zhou, Ahad N. Zehmakan, Zhongzhi Zhang
The Kirchhoff index, which is the sum of the resistance distance between every pair of nodes in a network, is a key metric for gauging network performance, where lower values signi…
Friedkin-Johnsen Model for Opinion Dynamics on Signed Graphs
Xiaotian Zhou, Haoxin Sun, Wanyue Xu +2
A signed graph offers richer information than an unsigned graph, since it describes both collaborative and competitive relationships in social networks. In this paper, we study opi…
Viral Marketing in Social Networks with Competing Products
Ahad N. Zehmakan, Xiaotian Zhou, Zhongzhi Zhang
Consider a directed network where each node is either red (using the red product), blue (using the blue product), or uncolored (undecided). Then in each round, an uncolored node ch…
Optimization on the smallest eigenvalue of grounded Laplacian matrix via edge addition
Xiaotian Zhou, Haoxin Sun, Wei Li +1
The grounded Laplacian matrix $\LL_{-S}$ of a graph $\calG=(V,E)$ with nodes and edges is a submatrix of its Laplacian matrix $\LL$, obtained fr…
