Network Topology That Excludes Braess's Paradox and Maintains Monotonicity in Flows Over Time
Xujin Chen, Xiyuan Deng, Changjun Wang
In the game of \emph{flow over time}, infinitesimal flow particles aim to travel from a source to a sink in a network as quickly as possible. Under the Vickrey bottleneck model, th…
Online Trading as a Secretary Problem Variant
Xujin Chen, Xiaodong Hu, Changjun Wang +2
This paper studies an online trading variant of the classical secretary problem, called secretary problem variant trading (SPVT), from the perspective of an intermediary who facili…
Supermodular Maximization with Cardinality Constraints
Xujin Chen, Xiaodong Hu, Changjun Wang +1
Let be a finite set of elements, be a nonnegative monotone supermodular function, and be a positive integer no greater than . This…
When does additional information lead to longer travel time in multi-origin-destination networks?
Xujin Chen, Xiaodong Hu, Xinqi Jing +1
The Informational Braess' Paradox (IBP) illustrates a counterintuitive scenario where revelation of additional roadway segments to some self-interested travelers leads to increased…
Favorite-Candidate Voting for Eliminating the Least Popular Candidate in Metric Spaces
Xujin Chen, Minming Li, Chenhao Wang
We study single-candidate voting embedded in a metric space, where both voters and candidates are points in the space, and the distances between voters and candidates specify the v…
Mechanism Design for Two-Opposite-Facility Location Games with Penalties on Distance
Xujin Chen, Xiaodong Hu, Xiaohua Jia +3
This paper is devoted to the two-opposite-facility location games with a penalty whose amount depends on the distance between the two facilities to be opened by an authority. The t…
